[Zope] Exception within ZServer hangs Zope

[Dennis Allison]

Jure --
What Zope are you using? what OS?  which python? what machine?  That
information is need to help sort out the problem.  Is this something 
that just started happening in a system that has been running for a 
while without a problem?  Have you recently upgraded either Python or
Zope?  

The exception happens in the guts of ZServer during a close when a unicode
string is found on a fifo. I suspect that changing the test to allow
ignore unicode stings as well as traditional strings would solve the 
problem, but I don't know the code well enough to say for certain.
