-#WARNING: because it waits for the result from command 2 after sending every line, and especially if command 1 does the same, using sentserver as command 2 won't actually buy you any real parallelism.

-DEBUG=1 env var enables debugging output.
-CROSS=1 hooks up two processes, 2nd of which has one line of output per line of input, expected by the first, which starts off the communication.  crosses stdin/stderr of cmd1 and cmd2 line by line (both must flush on newline and output.  cmd1 initiates the conversation (sends the first line).    default: attempts to cross stdin/stdout of c1 and c2 directly (via two unidirectional posix pipes created before fork).
-SERIAL=1: (no parallelism possible) but lines exchanged are logged if DEBUG.
-if SNAKE then stdin -> c1 -> c2 -> c1 -> stdout.
-if PIPE then stdin -> c1 -> c2 -> stdout (same as shell c1|c2, but with SERIAL you can see the intermediate in real time; you could do similar with c1 | tee /dev/fd/2 |c2.
-DIRECT=1 (default) will override SERIAL=1.
-CROSS=1 (default) will override SNAKE or PIPE.
