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.

Cheers,
entropy
