[Libguestfs] nbdkit worker thread shutdown

Hello, When nbdkit calls a plugin's unload() method, is it guaranteed that all pending requests have been handled (and all worker threads exited)? (I would have expected this to be the case, but I'm getting errors from threads accessing data that my unload() handler frees, so I wanted to confirm my assumption).
