Which operating system and version?

What does the mod_python startup message in the Apache error log file
say in regard to the number of session mutexes created. For example:

[Wed Mar 15 15:47:15 2006] [notice] mod_python: Creating 8 session  
mutexes based on 150 max processes and 0 max threads.

Is your Apache configured for prefork MPM or worker MPM?
