Great.

I found one more thing after I sent this patch though - the test for
osutils.rmtree tries to delete a readonly directory containing a
readonly file.  This doesn't work using python's rmtree, which is what
we use on posix - we'd need to write a replacement that makes the
directory writeable before trying to remove things inside it.  

For now I'm just going to stub this out of the test and test only
removal of a tree containing readonly files.
