[Zope] Persistant Zombies and a sanity check

[Dennis Allison]

I use htmldoc to generate pdf documents connecting to Zope via a simple
popen2() call in an external procedure which pipes input to htmldoc and
grabs output from htmldoc.  The htmldoc process remains in the process
table as a zombie and remains there until Zope is restarted.

To avoid persistant zombies, I'll need to not use the factory function, 
popen2, and do a bit closer management of the process--that is, the parent
will need to iexecute a wait on the child (htmldoc) so that when it
completes the child process can die.

Am I missing something?
