What I and others need is a continuing (non-blocking) conversion with 1 and
only 1 subprocess (see my response to Josiah), and that is much more
difficult. So this code does not do what he claims his will do.

I tried to write the shortest example showing how to read and send data and
how to make the call blocking. It's different to communicate() because
write occurs after the first read.

It should be quite easy to enhance my example to execute more commands.
