IrisEntity.spawn waited on J.sfut(...).get() to move the spawn point below
ground. J.sfut schedules the task for the next main thread tick, so when spawn
already runs on the main thread (ambient spawning in WorldEntitySpawner) the
future can never complete and the server stops ticking. Run the check inline
when already on the main thread.
