[PATCH libnbd] examples: Include an example of integrating with the glibc main loop.
** NOT WORKING **
This patch shows how to integrate libnbd and the glib main loop.
Posted mainly as a point of discussion as it doesn't quite work yet.

[PATCH libnbd v2] examples: Include an example of integrating with glib main loop.
This is working now, and incorporates all of the changes in Eric's
review, *except* that it still doesn't retire commands (although this
seems to make no obvious difference, except possibly a performance and
memory impact).

[PATCH libnbd v3 0/2] lib: Implement closure lifetimes.
I think I've addressed everything that was raised in review.
Some of the highlights:
- Callbacks should be freed reliably along all exit paths.
- There's a simple test of closure lifetimes.
- I've tried to use VALID|FREE in all the places where I'm confident
that it's safe and correct to do. There may be more places. Note
this is an optimization and shouldn't

[PATCH libnbd 0/7] Add free callbacks and remove valid_flag.
As proposed here:
https://www.redhat.com/archives/libguestfs/2019-August/msg00130.html
I didn't actually read Eric's replies to that yet because I've been
concentrating on writing these patches all day. Anyway here they are
and I'll look at what Eric said about the proposal next.

[PATCH libnbd v2 0/5] lib: Implement closure lifetimes.
v1 was here:
https://www.redhat.com/archives/libguestfs/2019-July/thread.html#00231
The changes address everything that Eric picked up in his review of
the first two patches. I have also added two more patches (4 and 5)
which respectively fix docs and change int status -> unsigned status,
as discussed.
Passes make, check, check-valgrind.

[PATCH libnbd 0/4] Add free function to callbacks.
Patches 1 & 2 are rather complex, but the end result is that we pass
closures + user_data + free function in single struct parameters as I
described previously in this email:
https://www.redhat.com/archives/libguestfs/2019-August/msg00210.html
Patch 3 adds a convenient FREE_CALLBACK macro which seems a worthwhile
simplification if you buy into 1 & 2.
Patch 4 adds another macro which is
