* Merge transform directory from sv-match-alignment branch
(the previous comment included notes for this stuff, but I missed it
in the actual merge)
* Fix crash when a transform fails to create an output model and the
thread that created the transform then deletes its input model thinking
it's no longer needed, even though the transform run thread is still
using it -- fix is to wait() on the transform before returning the
null output model
