The supervisor now records the process exit time and forcibly closes any sockets still open after `workers.task_supervisor_socket_cleanup_delay`. This stops the supervisor loop from hanging indefinitely and allows the process to exit cleanly.

The supervisor now records the
process exit time and forcibly closes any sockets still open after
