If you are on a Linux/UNIX system I would not suggest using a polling method at all. Most UNIXes now provide a kernel level notification system that you can register with to tell you if a file has been accessed. In Linux it is called [inotify][1], and there is a Perl module that allows you to use it: [Linux::Inotify][2].
