There is a big difference between having an emergency hatch that
gives you a chance to escape certain death by running across a
shooting range, and on posting a sign telling people to use it as
a short-cut.

debugflags&16 has legitimate uses if you know exactly what kind of
shitty situation you are in, and it should absolutely be in the
release kernel for that reason.
