I updated bfs.patch with improvements on Windows XP. 

The update disables priority boosts associated with the scheduler condition on Windows for CPU bound threads.

Here is a link to ccbench results:
http://bugs.python.org/file17194/nir-ccbench-xp32.log

Summary:

Windows XP 32bit q9400 2.6GHz Release build (no PG optimizations).
Test runs in background, ccbench modified to run both bz2 and sha1.

bfs.patch - seems to behave.

gilinter2.patch
single core: high latency, low IO bandwidth.

dabeaz_gil.patch 
single core: low IO bandwidth.
4 cores: throughput threads starvation (balance), some latency, low IO bandwidth.
