This was caused by changeset b6d0fa8c7685, and the traceback only happens:
1) You run setup.py on Windows
2) You have a compiled osutil.pyd is in the mercurial directory

The osutil.pyd is picked up by Python before the pure/osutil.py and
the only way I've found around this is to delete the pyd before
running my installer build scripts.

Anyone know of a Python friendly solution to this?
