## Message

```
Fix race conditions with LSP requests that return buffers

* Avoid panic when registering a buffer that was previously open,
  and whose weak handle was still present in the open_buffers map.
* Avoid releasing any buffers while a request is outstanding which
  could return a reference to a buffer.
