Callers may now optionally set up a concurrent writer thread. The outline of this idea is explained here: https://www.redhat.com/archives/libguestfs/2019-June/msg00010.html The change is quite small, but here are some points which are true but may not be obvious: * All writes return immediately with success (unless we run out of memory), and wri...

There are several races / deadlocks which I've thought about. Let's see if I can remember them all ... (1) This I experienced: nbd_aio_get_fd deadlocks if there are concurrent synchronous APIs going on. A typical case is where you set up the concurrent writer thread before connecting, and then call a synchronous connect function such as connect_tcp. The synchronous function grabs h->lock, then writes something, which eventually invokes the writer thread which calls nbd_aio_get_fd and deadlocks on h->lock. -> Probably the writer thread should...
