run_erl: Fix failing run_erl invokation on OpenBSD
Symptom: run_erl does exit(0) and child program (erl) does
not seem to start. Running run_erl again however brings the previous
child program to life.
Problem: A race causing run_erl to read 0 from master pty and exit
because the child has not yet opened its corresponding slave pty.
Solution: Use the non standard openpty() function instead that does
not expose this race as the slave fd is opened in the parent.
Question:
Is there a race free way to do this with posix_openpt on OpenBSD?
