Thanks for the thoughtful explanation of my massive thinko. While
camping on a filehandle late one night I bumped into a blocked loop...

The code destined for actual use is a mite smarter 'n that -- because
you wrote most of it. It's using Linux::Inotify2, AnyEvent, and IO::AIO.

The funny part: I'd thought that I'd leave the part that the 'tail -F'
was supposed to emulate until later because it's something I know well
and I was eager to get into the newer, funner stuff. Oops.

Thanks again, and be well!
