This is platform dependend, and frankly I'm not much of a thread expert. I
know on FreeBSD you will get unresolved symbols at link time when trying
to mix threaded and non threaded code. This is because it links against
separate versions of C libraries.

I don't know if this applies to Linux or Solaris. I know some people have
reported segfaults on RH if mod_python is not the first module listed, and
I have a suspicion that it is thread-related.

So that warning is exactly that - just a warning.

Perhpas someone on this list more knoledgeale on the subject can shed some
light on this?

[P.S. lest someone reading this gets the wrong idea - mod_python *is*
thread safe, it couldn't run on Win32 if it wasn't]
