WatchService - Exposing more of the Inotify Event Model

Thanks. I see your point and agree.

At the risk of sounding like a desperate software peddler, how about this idea?

A WatchEvent.Modifier implementation that enables you to register a
regular file (as opposed to a directory) with a WatchService.

E.g.,
    someRegularFile.register(watchService, watchEvents,
ExtendedWatchEventModifier.REGULAR_FILE);

I believe with the current WatchService implementation you would need
to filter any events received from a registered directory to look for
your one file of interest. I tested this concept on Linux but I'm
unsure if it would work with the native file system event facilities
on Windows or Solaris.
