[Zope] zombies with htmldoc

[Dennis Allison]

Running htmldoc via an External Method that uses popen2() under zope
2.6.2b3 and python 2.1.3 (both by the book...) I get zombie processes that
just hang in there...  Now zombie processes exist when a parent does not 
wait() for a child, so the problem would look like it's in popen().  The
htmldoc process seems to run to completion and generate the expected
output.

I seem to remember there were problems with popen, but a quick browse of
the python bug list didn't turn up anything.  Anyone else seen this
behavior?

Oh, yes -- the OS is RH9 and the machine is a dual processor Athlon.  I
suspect some OS related problem since this same code works without
creating Zombies on RH7.3.
