This is v3 of mt server thread management cleanup series.
changes include:
- splitting out a couple of patches, and moving simple bugfix to the
front.
- Fixed a bug in previous series where lockd module count was being
incremented when the lockd thread started, but not decremented when
it exited.
- minor improvement to patch descriptions.
Thanks for the review and testing!
