When running a load of mainly 2i queries, there is a huge cost in the
previous snapshot code.  The time taken to create a clone of the
Penciller (duplicating all the LoopState) varied between 1 and 200ms
depedning on the size of the LoopState.

For 2i queries, most of that LoopState was then being thrown away after
running the query against the levelzero_cache.  This was taking < 1ms on
average.  It would be better to avoid the o(100)ms of CPU  burning and
block for o(1)ms - so th eorder of events have been changed ot filter
first so only the small part of the LoopState actually required is
copied to the clone.
