I work in a fairly python-centric environment, we use FreeBSD for all of

Recently we have started using the following patch to python 2.5.2 in
production, and it's solved some issues we've had with regards to
python, FreeBSD, threads, and signals.
I've been contemplating whether it should be included in the FreeBSD
port tree or not, and if it's included whether it should be optional, so
on and so forth.
Here's the patch

Which versions of FreeBSD are you using this on? There are several
FreeBSD thread related issues in the Python bug tracker and it would be
useful to see if they can be squashed for the prospective 2.5.3 and 2.6.1
releases...
