yeah, i've heard similar things.  unfortunately, i haven't found where
in the standard is that defined.  Also, it's not clear if that
"regular files are always ready" requirement is just for select(), or
also for other polling syscalls.  in short, is there _any_ way to
really check readyness of regular files?
