It used to be that shutdown was "instantaneous" (2, 3 seconds or so). So when all of a sudden my shutdown time became 20 seconds I got interested. Why the wait?

Questions: What is your shutdown time?

According to the system.log from yesterday's shutdown (other shutdowns are similar):

Apr 9 22:57:38 Fiona shutdown[431]: halt by ...:
Apr 9 22:57:38 Fiona shutdown[431]: SHUTDOWN_TIME: 1207774658 599340
Apr 9 22:57:38 Fiona com.apple.loginwindow[36]: Shutdown NOW!

Interesting... Illegal instructions, Unknown error code. Why is Spotlight always working at the moment of shutdown? What is happening in the unshown 10 seconds?

Any clues out there?
 
Definitely: Malicious daemon process! Possibly: Buggy driver such as M-Audio USB MIDI

A precise investigation is hard, because launchd tells that the shutdown process was delayed, but not why!

Hence the troublemaker can be any software which gets started by launchd as a daemon process (permanent background application).

I had the problem, and my troublemaker was a malfunctioning USB MIDI Driver from M-Audio, which as a side effect even deactivated my boot manager rEFIt!

After deinstalling the flawed driver, everything worked fine again.
