I don't think there are any critical fixes here.  If it's easier to
drop this cleanup and just jump straight to the final version, that's
fine with me too.

I don't see anything in the their docs claiming optimizations [1], but
they do have a C implementation [2], so there must be something they
don't like about os.path.join.  I doubt any optimizations would matter
to us, since Python-side path joins are going to be a miniscule part
of any catalyst run.

I don't think it really matters.

Which issues?  Just assigning the paths to new variables?  I'm fine
with this commit doing that, regardless of style, and will happily
submit any PEP 8 cleanups I think we need after master has finished
swallowing 3.0 ;).

Pulling it out into a class sounds good to me, but if it's easier to
land this first (after fixing the exists() typo) and submit the
class-based autoresume later, I'm fine with that.  I wanted to point
out possible style changes, but none of that needs to be settled by
this particular patch.  I think the removal of duplicate path
calculations is a step in the right direction.

Cheers,
Trevor
