You assigned this to right guy even if he lacks some knowledge. :-) We can discuss more details
next week.

> We need a few LSM R-tree test cases where we have many leaves worth of data (which could
be achieved by making an artificially small NC config?) that have the same key - to make sure
that we can handle that case properly.  (I'm wondering after talking with Wail if that's the
root of his problems a few weeks ago - he had a high duplicate rate.)  E.g., we should trying
to insert a ton of data all at one of the same 2-3 unique spatial points.  It would be good
for there to be enough data that multi-level Hilbert sorting is required as well.  This is
likely to be a time-consuming test so it should be in our period (not per-checkin) tests.
 We should actually do this extreme-dup-case test for all index types, but R trees are suspected
of maybe doing this wrong.  Who would be best to write/run this test w/o much effort?
