FWIW, zombies are fairly light-weight processes :-}
They are really skeletons of what the process was: essentially enough
state information so that the parent can "reap" them and collect the
status information (I think it amounts to a process descriptor in the
kernel), so even 300 of them shouldn't be a drain (despite
Hollywood's unflattering depiction of them :-}).
It does pay to get rid of them, of course.
