+;;; FIXME: This is (almost) a direct copy of `with-displaying-help-buffer'
+;; that exists only in 21.5 core.  When 21.5 is stable I'd suggest
+;; that this macro be removed and the call to it in `profile-results'
+;; (see fixme comment in that function) below be changed to use the
+;; macro in core.  This is here because the packages are built with
+;; 21.4 so when this file is byte-compiled it doesn't include the
+;; definition of the `with-displaying-temp-buffer'.  Which was OK for
+;; 21.4 users, but 21.5 users would lose. --SY.
