No.  But I do have to say, I would rather the laptop suspend and kill my
download or file move than have it catch fire in my backpack (i.e. I
closed the lid while it was doing something inhibiting the suspend). 
Surely auto-suspend operates differently than when *I* tell the machine
to suspend (i.e. closing the lid, or clicking suspend).

This whole conversation, I assumed, is about _auto_suspend, not manual
suspend, right?
