uncommit: saner locking scheme (and do it in the right order in the process)

prune: lock inside the try tss…

debugrecordpruneparents: release tr the same way than the lock Nicer code is nicer.

evolve: drop useless wlock in rewrite

divergence: actually use the hint that have been around for age Having a hint in the code is good, having it displayed is usually seens as better.

evolve: rename `tr` variable (for troubled) to `tro` tro is usually dedicated to transaction.
