Releasing the cacke before sending result is mandatory if we want to be
able to use overlays (or revitalize Luke's idea of allowing code
insertion when entries are already (pre) or still (post) locked; this
would allow many features that require atomicity to be introduced by
means of overlays.
Also, note that most of the backends could give up the compare op; if
it's not available, the frontend provides a safe replacement. I only
fixed this because it was making the test fail...
