# The basic test structure here is that we write a lot of log
# records (enough to fill up 100 log files; each log file it
# small). We take periodic checkpoints. Between each pair
# of checkpoints, we refer to 2 files, overlapping them each
# checkpoint. We also start transactions and let them overlap
# checkpoints as well. The pattern that we try to create is:
# ---- write log records----|||||--- write log records ---
# -T1 T2 T3 --- D1 D2 ------CHECK--- CT1 --- D2 D3 CD1 ----CHECK
# where TX is begin transaction, CTx is commit transaction, DX is
# open data file and CDx is close datafile.
