Ah, excellent. That does indeed appear to work. I'm using brew and this is
the first time I've compiled from source instead of using a pre-built
binary. I assume that is what caused the difference, not code changes in
emacs HEAD.

Unless this is actually a gfilenotify <-> emacs problem(rather than a
gfilenotify on mac problem) I'd consider this solved/not a bug. Sorry for
wasting time!

Thanks,
Christopher Carpenter
