[Zope] EAGAIN errors crashing ZServer Aiieeee!!!!

[Michel Pelletier]

Hmm, a simple test script seems to indicate that sending a child process
a signal 11 does not cause it to dump core.  Of course, it also does not
seem to cause it to return a status code of 11 either.  This might not
be a SIGSEGV, it might just be a coincidence that the return code of the
(crashed) child is 11.  (FYI, there are two processing going on here, a
'watcher' parent and a child, the parent prints the 'Aieee!' when the
child dies.

Does anyone out there know what a python program returning 11 means?
