Not that simple. The .shutdown would need to perform more resource cleanups of the .remove call to prevent side effects. I need to move some of the .remove activity into the .shutdown handler to make sure the adapter is quiesced. I will hold off on submitting any of these changes until they are evaluated and tested; I am waiting for feedback from Yinghai on the other mitigations that I feel are closer to the root cause.
