Opens a pair of connected pipes like the corresponding system call.
Note that if you set up a loop of piped processes, deadlock can occur
unless you are very careful. In addition, note that Perl's pipes use

See IPC::Open2, IPC::Open3, and Bidirectional Communication in perlipc for examples of such things.
