In the patch I submitted, the pread() calls will fail on FIFOS, and
a normal read will be issued instead - so both should be fine (needs

I am convinced that multiple simultaneous async read/writes need to
be supported. Moreover, the ReadFile()/WriteFile() calls need to
work on sockets, therefore two separate implementations are out
of the question.
Of course the goal should be to make this work using as much of the
existing code as possible.
