Hrm... there are other alternatives.

[For example, plan9 has a call to read from a set of file descriptors,
using a "random but fair" policy.

Unfortunately, I don't remember the exact name of the call off the top
of my head nor do I remember its exact semantics. However, I have the
impression that it's easier to code into an event loop than select().
