[nbdkit PATCH 0/2] More caching of initial setup
When I added .can_FOO caching in 1.16, I missed the case that the sh
plugin itself was calling .can_flush twice in some situations (in
order to default .can_fua). Then right after, I regressed it to call
.can_zero twice (in order to default .can_fast_zero). I also missed
that .thread_model could use better caching, because at the time, I
did not add testsuite coverage. Fix that now.

[nbdkit PATCH 0/5] Counterproposal for python v2 interfaces
As mentioned in my reviews, I wonder if we should make our python
callbacks look a bit more Pythonic by having kwargs added for each
new flag that we want to expose. The idea was first floated here:
https://www.redhat.com/archives/libguestfs/2018-April/msg00108.html
Note that with my proposal, there is no need for a python script to
expose a global API_VERSION variable; new flags are added
