`inotify` (on Linux) and `kqueue` (on OSX), and a slower but more reliable "stat polling" method.  `inotify`/`kqueue` is less reliable because it does not work on every system, and sometimes `meteor` can't even tell if it doesn't work. Stat polling is slower in two ways: it only looks for changes once every "polling interval", and the actual check that it does consumes more CPU.

By default, `meteor` uses both `inotify`/`kqueue` and stat polling, with a polling interval of 5 seconds; if it detects...
