[libvirt] [PATCH 0/3] child process cleanups

[Eric Blake <eblake redhat com>]

In preparing for making iohelper useful with O_DIRECT fds, I
noticed a resource leak on failure in fdstreams.  Further
investigation found that most clients of virCommandRunAsync
passed a NULL pointer, and the only one that didn't was
risking closing an unrelated process under a pid reuse scenario.

Eric Blake (3):
  command: introduce virPidWait, virPidAbort
  fdstream: avoid child process leak on error
  virnetsocket: use new API for uniform child cleanup
