(ITS#3510) ACL evaluation short-circuit would be nice

Perhaps ACL evaluation could be short-circuited for "access to *".

Given a simple ACL configuration of:

access to *
    by users read
    by * none

on a heavily loaded machine, a search for "(objectClass=*)" takes a few seconds
to return as each entry is checked against the ACL rule.

It would be nice if an anonymous client could not consume server resources so
