Hi Marcel,

Thanks for your answer! It's good to hear that those other issues have been resolved. It is
likely that we'll try the fine grained locking strategy for production, but before that we
will run an number of load and/or stress tests. If we find other issues we'll share them :)

Best regards
Martijn
