Hash: SHA1
I work in a fairly python-centric environment, we use FreeBSD for all of
our production machines.
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
