Merge branch 'master' of https://github.com/drewmccormack/ensembles
Removed recently added locking of the event store. Doesn’t really solve problems, and it could cause deadlocks.
Refactored event builder so that the save monitor can create and commit its event atomically, in a single performBlock…
Previously it was spread over several blocks, and it is thought this may have caused a race condition with the rebaser, which would process a half made event.
