(I assume mod-active does already pause the server correctly.)
Unfortunately there is no _real_ lock in innd - ctlinnd commands can
access the history despite pause and that is a well known race
What would be needed: rewrite all the parts which need locking so that
reserve/pause becomes reliable and all parts observe a common
protocol. That would be a major change in some places. It would also
raise the question how to handle ctlinnd commands which wait for the
lock in a uniform way.
