Sure I understand that, but If I wanted it to be within 15 seconds

Usually any machine that can handle actually doing a job will have no
problem with the work checking and not doing it the rest of the time...
If you are concerned about it, a stat() is pretty cheap compared to
starting a program to do it, so you might write a long-running program
to monitor for a new file or a timestamp change instead of starting one
every few seconds. If you really want a file-event driven interface you
might look at dazuko. http://www.dazuko.de/faq.shtml
That's not a very good thing to do in a virtual machine (by way of
example). Contemplate doing this in a zSeries box where there are likely
100 or more virtual machines.
