Log Out means "stop"

I happen to agree with arogge, I think when you log out, it should quit everything, and log out. I mean you dont really "accidently" log out, its a couple of clicks.
I've run into the problem a few times, but if you force quit the app, it usually works fine. Sounds like your having bigger problems though. Glad you found a solution.

I've tried the "UPS" shutdown, but the problem was that the OS sometimes wouldn't power-off and the battery drained. When the battery drains, it becomes useless and tends to weaken such that it cannot be recharged. The battery systems now supply power to more than a PC, and I don't know during the start of an outage how long it will last. Maintaining maximum battery power is important, especially when the power can be out for a week. UPS systems take a lot of room and they're expensive. The "UPS" products that you might find in your local stores are not really uninterruptible. They provide minimal power for consumer electronics and quickly expire. A real UPS is designed to provide power for sensitive electrical devices until the utility power is restored. These batteries provided power for several days during a storm last year, keeping the consoles and other essential devices ready and on-line as needed. Perhaps with hydrogen fuel cells coming, smaller batteries will last for months or years.
Is this a home or a data center? 
Standard UPS systems, including the ones in the retail store, can hold your system up for about a half hour and they cost around $100 USD. That should be plenty of time to shutdown.
Another option is to put a diesel or natural gas generator out back.

Generators can be turned on, but they don't always provide the quality of power needed by sensitive hardware. The UPS systems that I need are not the ordinary consumer units. The battery housing of the additional unit that I'm considering for installation this year can be larger than a PowerMac.
Pardon my ignorance, but why don't you simply close the lid and put it to sleep? Why log out? If you've set the machine to require a password on resume from sleep, you'll get the same effect.
As a 50%/50% Linux/Mac user, I must say I prefer the Mac's logout behavior. I've lost data in OpenOffice more than once due to an overzealous WM sending it SIGKILL.

Closing the lid only works on portable systems with that function enabled. It's the servers that draw the most power, but try leaving a PowerBook in Sleep and its battery can drain in about three days, depending on temperature. The subject was about Shut Down, which to OS X is the same thing as "Wait for all applications to accept Quit before Shut Down." This is what Windows does, but the manual "shutdown -h" command works in OS X. Sometimes there isn't any time to waste while the OS leads the user through all the open applications, asking if you really want to close this app and force that app to Quit, and wouldn't you like to finish downloading your messages or check for Software Update patches? The OS X GUI is not responding to the command, and there's no option to turn off the "nanny" features. If I press Shut Down and then confirm by pressing Shut Down again, the OS should consider that a power-off command and shut down immediately, like it does from the Terminal.
Though generators are not reliable in providing clean power. You can add a line conditioner that would give you clean reliable power for computers. I don't know if you already have checked these out or if they are too expensive. When used in conjunction with a UPS and generator you would be able to stay online and not worry about shutting down rapidly for sudden power outages which seem to occur often in your area.
Unfortunately, a generator is not connected to this computer room. The line conditioners are integrated into the battery boxes, but they don't like low-quality power. There's several locations that have a similar issue. They have a diesel generator, but it's only connected to lighting, climate control, elevators, and one part of the server room. The individual users' consoles and remaining server banks are supposed to switch to battery and drop to low-power mode or power-off, so productivity is halted during an extended outage. The reason given is that there is insufficient fuel to supply power to everything. Maybe the budget for additional redundancy will increase next quarter, after we get hit by another round of storms.
