1. Forget BGW_NEVER_RESTART workers in
ResetBackgroundWorkerCrashTimes() rather than leaving them around to
be cleaned up after the conclusion of the restart, so that they go
away before rather than after shared memory is reset.

Now with this, would it still be required to forget BGW_NEVER_RESTART workers in maybe_start_bgworker():

                if (rw->rw_crashed_at != 0)
{
if (rw->rw_worker.bgw_restart_time == BGW_NEVER_RESTART)
{
ForgetBackgroundWorker(&iter);
continue;
}
                     ......
                }
