Re: [Libguestfs] [PATCH nbdkit] New plugin: blkio [incomplete]

(5) "The application is responsible for thread-safety. No thread synchronization is necessary when a queue is only used from a single thread. Proper synchronization is required when sharing a queue between multiple threads." Does this apply across multiple struct blkio handles? ie. Is there now, or could there be in future, some global state which would be corrupted by parallel calls across multiple handles? This matters because we could use NBDKIT_THREAD_MODEL_SERIALIZE_REQUESTS instead of NBDKIT_THREAD_MODEL_SERIALIZE_ALL_REQUESTS (https://libguestfs.org/nbdkit-plugin.3.html#Threads).
