Hey,
So, I started this little project, PythonPlus:
https://bitbucket.org/krisvale/pythonplus
Basically, I wanted to get out of my system some of the little changes that
we did at CCP to the python 2.7 thingie.
PythonPlus is the cpython repo, with some stuff added to the 2.7 branch.

At the moment, it is all threading stuff, designed at enhancing the
responsiveness of 2.7 when working with threads.

1) the locking primitives now all timeout, as they do in 2.x
2) there is a native RLock.
3) there is a custom GIL which makes CPU threads share load fairly and
ensures swift responsiveness for IO threads.
4) there is a native Condition impelentation, greatly reducing latency for
applications using Condition variables for signalling.  Previously,
threading.Condition was pure python with a lot of GIL thrashing, corner
cases, and overhead.

If you're interested, take a look.  A downside is that effectively support
is dropped for anything not Win32 or pthreads.

If there is a 2.8 project anywhere out there, then these things could be a
nice candidate.

Take a look at Tools/plus/giltest.py for code that excercises the gil, io
threads, and condition variables.

Cheers,

Kristj=C3=A1n
