I think this is the right direction. I mentioned in my last reply that
it would be nice for this to be a bit more generic, in case we need to
use it again (and also just to keep the module boundaries sane).
This part confused me at first:

since I thought you were actually turning things into absolute paths.
But your procedure is basically "turn absolute, then after chdir, turn
them back relative".
I think it might be clearer if a single call is given both the old and
new paths. That requires the caller of chdir() storing getcwd() before
it moves, but I don't think that should be a big deal.
