There are various locking calls available in the standard library.
Depending on what flavor of Unix and what file-system you are using,
some of them may be more appropriate than others...  I have a dot-locking
module that I've used fairly successfully.  It's called "jlock.py" and
is at ftp://ftp.tummy.com/pub/tummy/Python/jlock.py
