# TEST test044
# TEST Small system integration tests
# TEST Test proper functioning of the checkpoint daemon,
# TEST recovery, transactions, etc.
# TEST
# TEST System integration DB test: verify that locking, recovery, checkpoint,
# TEST and all the other utilities basically work.
# TEST
# TEST The test consists of $nprocs processes operating on $nfiles files. A
# TEST transaction consists of adding the same key/data pair to some random
# TEST number of these files. We generate a bimodal distribution in key size
# TEST with 70% of the keys being small (1-10 characters) and the remaining
# TEST 30% of the keys being large (uniform distribution about mean $key_avg).
# TEST If we generate a key, we first check to make sure that the key is not
# TEST already in the dataset. If it is, we do a lookup.
#
# XXX
# This test uses grow-only files currently!
