Detailed Description

Cache to store the Restrictions of every auth_id.

This cache is not thread safe. Callers must acquire acl_cache_write_lock before to amend the cache. Callers should acquire acl_cache_read_lock to probe the cache.

Acl_restrictions is not part of ACL_USER because as of now latter is POD type class. We use copy-POD for ACL_USER that makes the explicit memory management of its members hard.
