# The t2 table is unfortunately pretty contrived.  We need documents
# that are bigger than ROOT_MAX (1024) to force segments out of the
# segdir and into %_segments.  We also need to force segment merging
# to generate a hole in the %_segments table, which needs more than 16
# docs.  Beyond that, to test correct operation of BLOCK_SELECT_STMT,
# we need to merge a mult-level tree, which is where the 10,000 comes
# from.  Which is slow, thus the set of transactions, with the 500
# being a number such that 10,000/500 > 16.
