# #140 -- exercise the TEARDOWN path, which is where the bug lives.
#
# WHY THIS EXISTS: bench_common's bt_kill_ours uses `taskkill /F`.  That is a
# HARD kill -- no destructors, so ~LBE4ControlsManager / ~PadRIO never run and
# BTGlassPanels_Destroy (the function that saves, and the one that ran twice)
# is never reached.  Both of the first attempts died before teardown and the
# result looked like a difference between builds when it was really a
# difference in how far each run got.  A graceful `taskkill` (NO /F) posts
# WM_CLOSE and lets the dtor chain run.
#
# Pass a label; run it once on the pre-fix build and once on the fixed one.
