You can't (according to the ports) compile LinuxThreads on non-i386
platforms.

I am still trying to find out why python 2.3.4 will not compile and run
its test suite on FreeBSD 5/AMD64.  It runs for on i386, but not on AMD64,
it just core dumps when doing anything stack-heavy when compiled with
threading.  The fact it works with i386 and not AMD64 leads me to believe
it is a problem with FreeBSD, not python (works fine on -stable on i386
too).

The normal tricks on increasing the stack size for pthreads doesn't seem
to help at all.  I've tried linking against -libpthread, -libkse and
-libthr and all get the same results.  I've not tried it with -RC1 yet,
the latest was -B7.

I'm not sure if this is related to your issues or not, but I just wanted
to point out that I think there is a deeper issue with threads on FreeBSD
and so it may affect stuff other than python.
