When you shutdown the computer, the OS literally kills every process having the sudden termination flag set. Applications are free to set and unset this flag as they run. Typically, an application with no document open will set its sudden termination flag. But the flag is not set by default so applications can do proper cleanup.

That flag says "I don't need to do special cleanup upon exit, just kill 
me." I think that's different from isDaemon.
