Jukka Zitting commented on JCR-2699:
------------------------------------
I'm a bit worried about the potentially adverse effects of growing the number
of SystemSessions per workspace. A better approach could be to refactor the ACL
handling to use the ItemValidator.performRelaxed() mechanism from JCR-2714
instead of the SystemSession. I'd also take the ACL discussion to JCR-2573
where a more general effort to improve ACL evaluation performance is taking
place.
