I'm not convinced. What I did yesterday was a completely new
check-out, and I could binary search to 46638 in a repeatable way.

I will try again now with cache clearing - no, ATM I even don't
have a _cache.

Ok, the result is the same.
Exactly this change to pypy/tool/cache.py causes the errors.
After the change, the threading module can no longer import thread,
as like the stackless module no longer can import greenlet.

cheers - chris
