These processes have completed execution, but their parents have not  
read their exit status so they still have entries in the process  
table.  They'll more than likely be reaped when the parent process  
goes away.  If you'd rather not have zombies roaming around your  
system, use wait() to read the child's exit status.

If, after the parent process exits, these processes persist -- run  
'init -q' to get rid of them.

hth,
Michael
