#-------------------------------------------------------------------------
# Test cases 5.*
#
# Test that if a crisis-merge occurs that disrupts an ongoing incremental
# merge, the next call to "merge=A,B" identifies this and starts a new
# incremental merge. There are two scenarios:
#
# * There are less segments on the input level that the disrupted
# incremental merge operated on, or
#
# * Sufficient segments exist on the input level but the segments
# contain keys smaller than the largest key in the potential output
# segment.
