Thanks. I already managed to find an (unrelated) bug by exposing my code
to yours :-)
Side note though, while checking my OPT_INFO implementation, I
encountered a problem. I ran your qemu-nbd like so:
./qemu-nbd -x foo -D "test image" -t -p 18909 test.img
and then ran my nbd-client against it several times. At one point, I got
a SIGPIPE, because of:
qemu-nbd: io/channel.c:306: qio_channel_yield: Assertion `!ioc->read_coroutine'
failed.
this was during a debugging session, so there have been a few times where
I hit "k" in gdb, so the client was killed and the socket aborted. I'm
not sure whether that's related, but it could be -- and I thought you'd
want to know this.
I haven't been able to reproduce this either, so it might be something
complicated.
