Sort of like tripwire, but in real time.  The Amiga has a feature where
you could monitor a file or directory for changes.  Imagine cron
getting a signal when /var/cron/tabs changes.  Or any other daemon that
has a config file.  There's a description of the function (but not the
assosicated structures unfortunately) at

http://www.cs.man.ac.uk/~lucass/autodoc/dos.htm#StartNotify()

So, how many of you people _were_ Amiga hackers in a previous life?
