This is understandable but may be surprising to unix developers; maybe
you should put a note in osutils.py about this.

It seems, it's only present in osutils to give it a standard name that
saves callers from needing to work out whether to load the pyx or py
version. It would be a shame to replicate the
try:import:except:import everywhere, but you can certainly move it to
some other location.
In most cases we have say bzrlib.rio loading _rio_pyx. Possibly we
need stringutils or something more specific than osutils.
Alternatively perhaps what setup.py needs should be moved out of osutils.
