Unfortunately the Posix emulation environment in BeOS is extremely incomplete.
fork()/execv() are buggy, select() does not work with files/pipes and there are
numerous other problems. It would probably be possible to somehow "hack" pipes
in BeOS into our event system by using additional threads, but there was no
time for that for View/Pro 1.1. Perhaps in a future version, or if BeOS ever
gets a more complete Posix environment.
