Forgive my ignorance, but why do you need two pipes...in other words,
each pipe is an unidireccional channel between two ends; so you have to
give two endpoints (one of each pipe) to the process, and use the other
two to read and write.
what you're asking for could (in theory, i guess) would need sockets
(which are bidirectional). you creae a socket pair (using socketpair(),
of course), give one to the process creator and use the other to read/write
local sktA, sktB = socketpair()
local proc, err = os.spawn (stdio=sktB, ...)
-- use sktA to communicate
i don't know how hard would it be to make os.spawn accept a socket and
use it for both stdin and stdout...
