I think that is backwards, it works for you on Linux but not me on Win32
because of bzrlib.locks. dependency on _w32c_WriteLock. Do you agree?

Here is a copy of the output from trying your attached script on my Win32

I was going to try the new 'python -m trace --trace' trick ... on the output
of 'bzr-be'test.py' ... but the file is 20Mb.
I will re-read your email and try to help out from my end.
