[Haskell-cafe] Behaviour of System.Directory.getModificationTime

[Krzysztof Skrzętnicki]

If this is not a toy program I would really suggest using something that is
builtin in the OS of choice. On Linux there is inotify (
http://en.wikipedia.org/wiki/Inotify), but I'm pretty sure that other OSes
have similar interfaces. The "modification time" method seems really fragile
and I probably not very efficient as well.

Best regards,
Krzysztof Skrzętnicki
