mod_python and Apache 2.2.1 release candidate.

[Graham Dumpleton]

FWIW, mod_python (from subversion) passes all tests with the Apache  
2.2.1
release candidate on Mac OS X 10.4.

Previously the test_global_lock test failed with Apache 2.2.0 because  
of a
bug in the APR library on Mac OS X. Apache 2.2.1 has newer version of
APR library which fixes problem.
