-;;; FIXME: This variable is motivated by Gerd Moellman's observation,
-;;; in <867kga1wra.fsf@gerd.free-bsd.org> on cmucl-imp 2002-10-22,
-;;; that the functions returned from EMIT-xxx-FUNCTION can cause an
-;;; order-of-magnitude slowdown. We include this variable for now,
-;;; but maybe its effect should rather be controlled by compilation
-;;; policy if there is a noticeable space difference between the
-;;; branches, or else maybe the EMIT-xxx-FUNCTION branches should be
-;;; deleted. It's not clear to me how all of this works, though, so
-;;; until proper benchmarks are done it's probably safest simply to
-;;; have this pseudo-constant to hide code. -- CSR, 2003-02-14
