Detect File System changes

[Fuzzyman]

The proper way to do this is to use the facilities provided by the
operating system. This means the solution is going to be different for
different platforms. I've *not* done this before - but certainly for
Windows I've seen discussions about this in this group previously.

The win32 extensions expose this capability for windows. I hope this
helps your googling.

All the best,
