You might also want to do some google searching since there have been
some discussions recently that cover this in more detail.  In
particular, the "Critical sections and mutexes" thread, which
discusses this and includes some opposing viewpoints in terms of being
able to be more trusting of the thread-safety of the interpreter.

I think this URL will get you to the thread (not sure if it can be
simplified) - it's all one line:

http://groups.google.com/groups?hl=en&threadm=mailman.1003864103.32304.python-list%40python.org&rnum=1&prev=/groups%3Fq%3Dg:thl4080539814d%26hl%3Den%26selm%3Dmailman.1003864103.32304.python-list%2540python.org

Worse case searching for the subject should do it.  Looking for GIL or
global interpreter lock will probably turn up other references as
well.
