RE: cpu used too much



zombie processes are the remains of a process that exited.  The reason
they hang around is that the parent process didn't do a "wait" on them.
As soon as the parent process exits, the zombie should be inherited by
init and init will clean them up.  Zombie's don't use any cpu and they
don't use any memory.  The only thing left is the entry in the process
table.  They don't hurt you except if you fill up the process table with
them (in which case you start seeing "cannot fork" errors).  I suppose
there could be circumstances where you would expect zombies but it is
usually considered a bug in the parent process.
