When you send a message from the GPUConnection::connection()->sendWithAsyncReply (or sendWithPromisedReply), the reply will always be dispatched from the main thread. It can make for some surprising behaviour when a WorkQueueMessageReceiver expect an answer on its defined work queue.

A solution would be to have an override for `Connection::sendWithAsyncReply` that takes a SerialFunctionDispatcher on which the reply will be called on and pipe things internally to either dispatched the reply to Connection::dispatcher() or that defined SerialFunctionDispatcher.
