then this dispatcher needs to be threadsafe too. either way - you need to make
something threadsafe, and pipes/fd's already are :) personally i ask - why do
you need threads? threads are for people who can't schedule their own code (or
in rare cases when api's or syscalls literally may block for long periods and
you have no choice).
