This bit is going to change anyway when I add the PythonOption
mod_python.mutex_directory support. I have the changes ready, but I
think I'll review them in the morning rather than committing now.
I decide to do this stuff in 2 steps:
1. configure option
2. PythonOption mod_python.mutex_directory
PythonOption mod_python.mutex_locks
BTW, the commit seemed to miss newly generated src/include/mod_python.h and
any notes added to Doc/appendixc.tex. Graham
