0.6.12.39:
	removed some stuff checking for profile monotonicity (since
		now I know that OpenBSD get-internal-run-time *isn't*
		monotonic, since OpenBSD getrusage() isn't monotonic:
		bug kernel/1065. I've now patched my OpenBSD 2.9 to
		fix this enough to make GET-INTERNAL-RUN-TIME
		monotonic, and I'll submit the patch to the OpenBSD
		maintainers once I straighten out how to diff against
		the patch branch.)
	tweaked GET-BYTES-CONSED (aiming to minimize consing in
		profile.lisp)..
	..replaced *TOTAL-BYTES-CONSED* with
		*N-BYTES-FREED-OR-PURIFIED-PCOUNTER*
	..deleted *LAST-BYTES-IN-USE*
	..added DEFKNOWN GET-BYTES-CONSED
	..incompatible change: made GET-BYTES-CONSED return the
		number of bytes consed since the system was started,
		not since the first time the function was called
	..renamed GC-COLD-INIT-OR-REINIT, since it's only actually
		called at reinit time
	fixed *BYTES-CONSED-BETWEEN-GCS* FIXME; and now
		DEFAULT-BYTES-CONSED-BETWEEN-GCS no longer needs
		to be a named definition
	deleted unused *GC-INHIBIT-HOOK*
