The implementation of tail has a lot of little oddities to deal with
edge cases. Why not simply use it?

A while ago, I wanted to make a system that would tail a bunch of logs
on a bunch of computers, and display it all to me in a single unified
view. Rather than write something that opened a whole lot of files and
monitored them, I simply forked a 'tail' process for each file and
reacted to its stdout. It was way WAY easier than dealing with
everything that could possibly happen (log rotation, etc, etc, etc) -
not that it'd be impossible to deal with, but it's a waste of time
reinventing this particular wheel. Build on top of what's already
there, save yourself the trouble.
