# This test really needs some major surgery to be acceptable, but
# I'm just about burnt out on lynx work, so I'm not doing it now.
#
# * The test has an indeterminate number of pass/fails
# for each run (it runs a small group of tests until
# it's timer kicks off). This is very bad for nightly
# automated regression testing.
#
# * It tries to "step" from withint he prologue of a
# function. This isn't support in gdb (it's going
# to act like a continue).
#
# * This test rarely check that it stopped in sensible
# places. (see previous bullet -- this test doesn't
# catch the fact it continued rather than stepped)
