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.

actually, IRL the code works as expected. Might it be possible that the speed of test execution is greater than the granularity of the system's modification timestamp?
