In playing around with child processes connected to a parent thru ptys, sometimes the children survive the parent. When this happens, and I try to open the pty next time thru, the open("/dev/pty??", 2) call hangs. I didn't see anything about this in pty(4) but from reading the source to script(1) it seems to me that if a pty is in use open will fail, not hang. What am I doing wrong here? Also, is there some way to ensure that children don't survive the parent? thanks
