Follow-up Comment #2, bug #48149 (project octave):
If I don't write anything to the input side of the pipe, but instead read from
the output, then it returns -1. This seems to set the EOF on the pipe because
if I then write to the input side the output always returns -1.
It seems that this sequence is required
1) popen2()
2) write to input
3) flush input or close input
4) pause
5) read from output
