Not such good news. There are failures related to file handles, e.g.

C:\repositories\biopython\Tests>c:\pypy-1.9\pypy.exe test_BioSQL.py
Traceback (most recent call last):
  File "app_main.py", line 51, in run_toplevel
  File "test_BioSQL.py", line 705, in <module>
    create_database()
  File "test_BioSQL.py", line 96, in create_database
    os.remove(TESTDB)
WindowsError: [Error 32] The process cannot access the file because it is being
used by another process.: C:\repositories\biopython\Tests\BioSQL\temp_sqlite.db

This is likely down to slow handle release meaning the OS
won't let us delete open files (Windows specific - you can
do this on Linux and Unix fine).

I won't be adding this to the buildbot for now.
