Apache 1.3 is not threadsafe. In my experience, it will crash when it's linked
to the threading libs - which is what happens if you load a threaded version of
mod_python.

I've always had to build a separate python without threading support, for use
with mod_python, when I want to use Apache 1.3.

This is probably what you've done too, or the system has done for you (or the
guy who made the binaries did). Loading "threading" in Python when Python is
built without threading support might lock it up - that could be what you're
seeing.

Either way, you will have to switch to Apache 2.0 if you want to use threading
with mod_python. This is the nature of mod_python. :)
