[Zope] RE: Zope and mod_python

Well, I will check the options I used to compile python (I think it was
default options).

But I think that threading is mainly required for the Zope Servers (HTTP,
FTP, WEBDAV), which is precisely the part of the functionality we move to
Apache in the attempt I did (each child process runs a Zope instance that
only has one thread, i.e. that only handles one request at a time and that
only has 1 connection to ZEO).

Another place where threads were needed is ZODB, but again, in my attempt,
ZODB is handled in an external ZEO instance.

this is interesting. Last I tried, mod_python was NOT thread enabled,
and therefore would NOT work with zope which needed a threaded version
of python. Has mod_python gone threaded now?
