IIRC, inotify doesn't work on mounted directories. gfile uses what's
appropriate; on mounted directories (again, IIRC) it polls for changes
of the supervised file/directory.

On BSD-like systems, including MacOS X, you can use only gfile these
days from Emacs. There exist a native library kqueue which ought to
implement file notifications, but nobody wrote an Emacs integration so
far. And AFAIU, gfile uses internally kqueue on those systems (not
tested by myself).

I also don't remember whether there is inotify support for Cygwin.
