Improvements:
(1) Move bio into trso so we don't have to allocate/free it all the time.
    Saves on error recovery hassles if we can't allocate a bio.
(2) Interlock while we're doing things, so we don't duplicate each slab of work.
(3) Update metadata after each bundle of slabs. (mav: please comment on

(4) Transition state to active when we successfully
