On the one hand, this is a new lib, growing pains are to be expected, and HAL is still
available as a backup on many distros.

On the other hand, having a background process--any background process--consuming
constant and significant CPU is not desirable.

This could be justifiably labeled as a blocker bug, I think, since it's going to degrade
TDE's performance significantly on any distro not still shipping HAL.

That being said, Slavek is right--if in order to use notifications, we need to
know what signals and devices need to be handled.  Power management needs to 
know about AC being plugged in/unplugged and batteries being added/removed, 
I'd assume.  For automounting, we'd need to capture a whole bestiary of events:
plugging/unplugging of USB mass storage, sD and other similar cards, optical
disks, floppies . . .
