Yes, good idea.
State-wise, the existing flow was:
Created
- Progress only by command issue - namely one of nbd_connect_*
Connecting
- Progress by aio_notify_read/aio_notify_write (as driven by
aio_poll), and progresses through socket establishment, magic numbers,
and handshaking
Loop of:
Ready
- Progress by command issue (I/O commands) or aio_notify_read
Processing
- Progress by aio_notify_read/aio_notify_write, commands are queued
rather than causing st...

[PATCH libnbd v2 0/3] python: Add test for doing asynch copy.
v1 was here:
https://www.redhat.com/archives/libguestfs/2019-August/msg00103.html
In v2 I've made several changes:
- Fix Python callbacks so if they don't return something
which is int-like, we assume they mean to return 0.
- Add nbd.Buffer free() method. Read commit message in
patch 2 to see what this is about.
- Fixed the asynch copy test to deal with the unbelievably

[libnbd PATCH] API: Add nbd_set_opt_mode to expose NEGOTIATING state
This is the bare minimum needed to allow the user to take control over
the rest of option negotiating. This patch adds several new API:
nbd_set_opt_mode() - called during Created to enable the new mode
nbd_get_opt_mode() - query whether opt mode is enabled
nbd_opt_go() - used in Negotiating state to attempt to use export
nbd_opt_abort() - used in Negotiating state to skip Connected state

[PATCH libnbd 0/3] Use free callback to hold ref to AIO buffer.
Basically the same as this patch series, but for Python:
https://www.redhat.com/archives/libguestfs/2019-August/msg00235.html
plus adding the 590 asynch test at the end.

[PATCH libnbd] generator: Move first_version fields to a single table.
This doesn't include Eric's new APIs, but if you push those
then I can rebase this one on top.

[PATCH libnbd 0/5] WIP: python: Add test for doing asynch copy.
This doesn't yet work. However it does make me more convinced than
ever that we really need to sort out persistent buffer lifetimes in
the library (similar to what we did for closures).

[PATCH libnbd v2 00/10] Callbacks and OCaml and Python persistent buffers.
This is a combination of these two earlier series:
https://www.redhat.com/archives/libguestfs/2019-August/msg00235.html
https://www.redhat.com/archives/libguestfs/2019-August/msg00240.html
plus changes to allow .callback = NULL / .free != NULL, and to reduce
the complexity of freeing callbacks.
Although it's rather long there's nothing complex here. We might
consider squashing some
