New threading library & python

[Derek Tattersall]

I use spambayes, apython based bayesian mail filter.  Today I rebuilt
python 2.3 for no discernible reason, and spambayes failed 

--- Logging /home/dlt/mail/procmail.log for dlt, Fatal error 'Spinlock
called when not threaded.' at line 83 in file
/usr/src/lib/libpthread/thread/thr_spinlock.c (errno = 2)
procmail: Program failure (-6) of "/usr/local/bin/sb_filter.py"
procmail: Rescue of unfiltered data succeeded

My problem is that I don't really understand what the replacement of the
pthreads library with the kse library means, and I can't go dig it out
of the last couple weeks of archives.  I fixed it by rebuilding python
without thread and rebuilding py-bsddb to link to the new python.  

Could somebody explain a) what went wrong, and b) what is the correct
fix for this library problem?  And please copy me, as I am not
subscribed to this list.

Oh yeah,
