I don't care about any overhead associated with stuck processes, nor do I
care that they look ugly in the ps output. What I care about is the fact
that at least once a week on multiple systems with different hardware, some
HW-related driver/process gets stuck, then immediately cascades its
stuckness up to udevd or hald, and then I can't use any of my hardware
anymore until I reboot.
