e01efe02f6 Long snaphsot timeout increase 
Increase this to 90 minutes.  The first time all the snapshots are
rebuilt it may take a long time, but they all get scheduled together -
and queued until concurrency limits allow it to be completed.

currently the snapshot is made on initialisation, and only released
when completed (which may be after the queue).  so the last couple of
snapshots were over-shooting the 1 hour.

11ff3129f3 Reduce compaction targets 
Cmpaction is overly aggressive.  It is a lot of work to compact a run of
files for just 20% reduction in disk space, when disk space for the
Journal (i.e. low IOPS disk space should be relatively inexpensive).
Require at least a 40% reduction for a compaction job.

1fdcdf3b37 Midblock size - lookup

64e944d9ba Change to 5 blocks in SST Slot 
Change to 5 blocks is intended to make the blocks in lookup slots
fractionally smaller, but more importantly to introduce a middle block
that cna be opened in a binary-split style fashion to reduce the number
of blocks that need to be opened for range queries.   Worst case for
full slots is 3 blocks now not 4.

dd0316eedf Yield on query selectively 
Still not clear if yielding is the cause of memory problems, but taking
it away universally has impacted throughput.  At the very least we
should continue to yield on high-contention files (those at higher
levels), where the processes are more likely to be quickly terminated
anyway allowing GC to be invoked.

f20aba9c8b Curtail trimmed slot crazyness 
There was complicated and confusing code that achieved nothing for
effiency when trimming slots.  the expensive part (binary_to_term) was
still needed on every block, and it was hard to get code coverage and
make sense of what it was really trying to achieve.

This is now much simpler - and may set us up for potential further
indexing help.
