Or you could use FreeBSD 4.x with kqueue support. With an kernel queue
you can select() on any kernel event, including filesystems, files and
directories.
See the man page:
http://www.FreeBSD.org/cgi/man.cgi?query=kqueue&apropos=0&sektion=0&manpath=FreeBSD+4.2-RELEASE&format=html
and see 'tail' for an programming example:
