Hi Graham,

Thanks for the reply.  I'm using mpm-worker.  I tried the mod_python 
patch, but there was no change.  As far as third party packages, Quixote 
doesn't use threads as far as I know, and only has one C module.  ZODB 
has several C modules.  ZEO, which is on top of ZODB and where the 
exception is happening, creates threads via the threading module.

Do you have any suggestions as to what I should instrument to locate the 
problem?

Thanks,
-John
