efficient reverter
It is common for benchmark to alter a repository content (eg: pull/push, commit), and we need to efficiently revert its content before being able to run a new benchmark.
The current option is to make a copy and run a full rsync from the source. That option is slow (multiple minute) for large repository.
If we had something like a scrip tusing inotify to detect altered content and revert it at the end of the benchmark. It would be good.
