# ID: transaction_group_integrity_001_pos
#
# DESCRIPTION:
#
# Verify the integrity of non-aligned writes to the same blocks that cross
# transaction groups.
#
# STRATEGY:
# This test verifies that non-aligned writes are correctly committed to the
# file system, even adjacent transaction groups include writes to the same
# blocks.  The test runs through multiple repetitions in an attempt to trigger
# race conditions.
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: BEGIN (2011-10-20)
