I'm a bit unsure here, actually. So you lock a mutex, send a request, wait for a response, then unlock the mutex. Surely this code doesn't allow more than one request to be in flight at a time?
No, it doesn't. It shouldn't be hard to do it though. You could have two mutexes, one for sending and one for receiving. You yield after sending, and let nbd_coroutine_restart read the reply. It can then reenter that reply's coroutine based on the handle in the reply. I still prefer to do it in a separate patch.
