Well, there's no inotify, and no FAM on OSX, so neither really helps.
There is kqueue, but it's limited to something small enough that it
ends up falling back to polling anyways, IIRC.

In the end, what we need to implement on OSX is FSEvents support:
http://developer.apple.com/documentation/Darwin/Conceptual/FSEvents_ProgGuide/index.html
but it's 10.5-only, so we'd still need to fall back to polling on
10.4.  (Technically FSEvents exist on 10.4, but are a private API, it
didn't get promoted to an official API until 10.5).
