[Libguestfs] [libnbd PATCH 0/2] in_flight improvements

[Eric Blake]

Noticed while thinking about the recent threads wondering if we need a
more efficient lookup from cookie back to command.  Both of these fix
bugs, but are tricky enough that I'm posting for review.

Eric Blake (2):
  lib: Decrement in_flight at response, not retirement
  lib: Do O(1) rather than O(n) queue insertion
