Hello, Everyone
I've had it happen like this: let's say I'm using (or attempting to
use) my cd burner.  Sometimes on Fedora Core my USB burner would be
dropped for reasons beyond my understanding.  I would have to unplug
it, and plug it back in and all would be well.  If I FORGOT to do that,
I would end up with a zombie process of cdda2wav (or cdrecord if I was
burning a cd) and I could not use the burner (or that particular
application) until I got rid of the zombie process.  In the above
cases, killing the parent process would not touch it.  So, to get the
use of my burner back, I would have to reboot :(  I mention this in
reference to Jeffrey's statement about hoping they wouldn't be anything
to worry about.....  Of course, not all zombies are as stubborn as the
ones that I have had.....
