Comment (by skelly):

 Also doesn't happen when `build_wait_timeout` is set to 1.

 Checking the code it calls `self.insubstantiate()` when
 `build_wait_timeout` is 0 and then checks if builds need to be started.
 When `build_wait_timeout` is not zero, it starts a timer to call
 `self._soft_disconnect()`. In `_soft_disconnect`, the code calls
 `AbstractWorker.disconnect(self)` and then `self.insubstantiate(fast)`.

 Checking the `insubstantiate` method and it already checks if builds need
 to be started.
