# Things get iffy here; when we step, sometimes the step

# (wait_for_inferior just evaporates it).
#
# I think the right answer is that any failures here
# should stick around to trigger later fixing.
#
# Here's the plan:
#
# Bps at 148 (5) and 154 (6) on thread 7 (two bps so we
# see the difference between going around the loop and
# reporting the same bp hit twice).
#
# Bp at 144 on thread 3.
#
# Step out of a library routine.
#
# Either the step will finish or a bp will hit. Try to
# handle all the cases.
