# Test summary:
#
#   rtree3-1: Test OOM in simple CREATE TABLE, INSERT, DELETE and SELECT 
#             commands on an almost empty table.
#
#   rtree3-2: Test OOM in a DROP TABLE command.
#
#   rtree3-3a: Test OOM during a transaction to insert 100 pseudo-random rows.
#
#   rtree3-3b: Test OOM during a transaction deleting all entries in the
#              database constructed in [rtree3-3a] in pseudo-random order.
#
#   rtree3-4a: OOM during "SELECT count(*) FROM ..." on a big table.
#
#   rtree3-4b: OOM while deleting rows from a big table.
#
#   rtree3-5: Test OOM while inserting rows into a big table.
#
#   rtree3-6: Test OOM while deleting all rows of a table, one at a time.
#
#   rtree3-7: OOM during an ALTER TABLE RENAME TABLE command.
#
#   rtree3-8: Test OOM while registering the r-tree module with sqlite.
