This happens only +when run under ptest-runner and not when interactively testing! + +The changes made to fix this include: +1. Get the process group id (pgid) before forking, +2. Set the pgid in both the parent and child to avoid a race, +3. Find, open and set permission on the child tty, and +4. Allow the child to attach to controlling tty. + +Also add '-lutil' to Makefile.
