"Linux-only" is the problem there. I know Linux folk like to imagine they
define Unix and POSIX, but there are others out there still. Same problem
with BSD's kqueue: I can't use it on Linux and only to a limited extent on
OS X which has still another mechanism of its own (Mach ports).
It's the *portable* general event interface that is missing.
