[Libguestfs] [nbdkit PATCH v2 0/8] Support parallel transactions within single connection

[Eric Blake]

I've posted some of these patches or ideas before; but now I'm
confident enough with the series that it should be ready to push;
at any rate, I can now run test-socket-activation in a tight loop
without triggering any crashes or hangs.

With this in place, I'm going back to work on making the nbd
forwarder wort with the parallel thread model.

Eric Blake (8):
  sockets: Use pipe-to-self to avoid hanging in poll
  cleanup: Add ACQUIRE_LOCK_FOR_CURRENT_SCOPE()
  connections: Add read/write lock over client I/O
  connections: Add thread-safe status indicator
  connections: Set up thread pool for handling client requests
  core: Add --threads option for supporting true parallel requests
  tests: Annotate Makefile.am conditionals
  tests: Test parallel behavior
