Why does this pass "1" instead of "0"?  The existing code does not give
refresh_cache() REFRESH_REALLY bit, and a patch that is marked as a pure
optimization should pass 0.  If you really mean it, please spell it as
CE_MATCH_IGNORE_VALID and justify why it is a good change in a separate
patch.

Thanks.
