I need a bi-directional FIFO

[Alan Grimes]

I am trying to get two instances of CGoban to talk to each other through
a fifo.

I mkfifo'd a pipe and have even managed to play a game up to 47 moves
through it but the protocol keeps dropping. I think that this is because
the stupid, idiotic, worthless, piece of crap pain-in-the-ass linux
kernel is far too brain-damaged to set up a unique queue for each
process... (Even DOS would have noticed two processes attempting to
access the file in an obviously wrong way and would have blown the
whistle on it -- come over to my house if you want a demonstration.)

before I disconnect my modem and install a serial loop-back cable, do I
have any software alternatives to this problem?
