New description:
The drop-upload feature (#1429) uses inotify to detect filesystem changes,
and therefore works only on Linux. This ticket is about supporting the
same feature on Mac OS X and possibly other BSD-based operating systems.
Mac OS X has the [http://en.wikipedia.org/wiki/FSEvents fsevents], and all
BSDs including Mac OS X have kqueue/kevent. If I understand correctly,
neither fsevents nor kqueue/kevent give notifications of which files have
changed, so the implementation will have to scan the directory and look at
last-modified times to determine that. (This is occasionally also
necessary for correctness on Linux; see #1430.)
