# - rev_10 produced good result "2000" -- this is current baseline
# - rev_20 completely broke the build (say, result "10")
# - rev_22 fixed the build
# - rev_30 regressed the build to result "1000" -- this is the regression we
# detected vs "2000" baseline.
#
# The script will identify rev_20 as the first failing commit, which will
# cause the baseline to be reset to rev_20 with metric "10". When we then
# rebuild master (at rev_30) we will see a /progression/ from "10" to "1000",
# thus missing the regression of "2000" to "1000".
#
# To catch the "2000" to "1000" regression someone would need to manually
# trigger bisect between rev_22 and rev_30.
#
# TODO: We could skip revisions (exit 125) that are worse than metric
# for $bad_rev (result metric <1000 in the above scenario), so we would
# skip revisions between rev_20 and rev_22. This might cause other edge
# cases to be handled sub-optimally, though.
