Or, y'know, me. :-)
A zombie is a process that is a child of some other process (though all
processes are, eventually, children of root) and has exited, but it's
parent has not yet wait(2)ed for it.
It is kept around in the process table so that when that parent process
*does* get around to calling wait, the appropriate information is still
around to give it.
