[comp.unix.wizards] Portable inter process communication

jh@pcsbst.UUCP (11/29/87)

Pay attention to the deadlock dangers when communicating with
pipes in both directions. If both pipes block writes because
they are full a deadlock is caused.

It is *very* hard to avoid this in general. In some cases
you can set up a protocol which uses packets up to a
certain size (PIPSIZ in some implementations).
