- Hm, OK, I'll accept it as a tentative solution.
-
- My only problem with it as a permanent solution is that a process
- hanging around in the foregroung process group could prevent the
- controlling tty from ever being released, causing the
- you-only-get-one-login-per-device problem again. One way this could
- happen is if an asynchronous process is spawned from a
- non-job-control-aware shell (e.g. one that knows nothing about process
- groups). I guess this isn't a big enough problem to be concerned
- about at the moment, unless there are other ways this could happen.
