> Oh, I like this idea. It looks like this can ben done rather easily on platforms that support libdispatch by creating a dispatch source of type DISPATCH_SOURCE_TYPE_VNODE. There are also FSEvents on the Mac, but it can only monitor a directory whereas DISPATCH_SOURCE_TYPE_VNODE lets you monitor specific files.

To correctly monitor the “contents of file at this path” you might need to monitor both the contents of the file and the contents of the directories in the path.
