# This is gutsy -- we're assuming that mutex_enter(9F) will show up in the
# output. This is most likely _not_ to show up in the output if the
# platform does not support arbitrary resolution interval timers -- but
# the above script was stress-tested down to 100 hertz and still ran
# successfully on all platforms, so one is hopeful that this test will pass
# even in that case.
