# TEST	sdbtest002
# TEST	Tests multiple access methods in one subdb access by multiple
# TEST	processes.
# TEST		Open several subdbs, each with a different access method
# TEST		Small keys, small data
# TEST		Put/get per key per subdb
# TEST		Fork off several child procs to each delete selected
# TEST		    data from their subdb and then exit
# TEST		Dump file, verify contents of each subdb is correct
# TEST		Close, reopen per subdb
# TEST		Dump file, verify per subdb
# TEST
# TEST	Make several subdb's of different access methods all in one DB.
# TEST	Fork of some child procs to each manipulate one subdb and when
# TEST	they are finished, verify the contents of the databases.
# TEST	Use the first 10,000 entries from the dictionary.
# TEST	Insert each with self as key and data; retrieve each.
# TEST	After all are entered, retrieve all; compare output to original.
# TEST	Close file, reopen, do retrieve and re-verify.
