It seems Apple may have changed something in the latest SSD-based notebooks and/or Mountain Lion?
I have "safesleep" disabled currently:
$pmset -g | grep hibernatemode
hibernatemode 0
The default for laptops is "3" which writes an 8GB or 16GB image of RAM contents to disk, depending on how much RAM you have installed.
Once you set it 0 you're supposed to be able to delete the sleepimage file and it never comes back.
More info here:

However, even with hibernatemode 0, the "sleepimage" file keeps getting re-created upon reboot or resume from sleep. On my other mac laptops, the file isn't recreated again once its deleted.
Anybody else with a rMBP (or 2012 Air) try this?
