I'm able to get Zope to dump a core file if run in debug mode ('-D').  I
haven't proved this, but I suspect that when a fork()ed child dies it
does not dump a core file.  Since debug mode does not cause Zope to fork
off Zope as a child from the parent watchdog, a core file is produced. 
None of this is mentioned on the fork() man page, or the clone() man
page, or whatever.  I probably need a good UNIX programming reference to
verify it.

Give it a try, fire up Zope in debug mode and run your load scripts
against it to reproduce your segfault.
