Subject: [PATCH] Bug #1491: clientLifetime exceeded + external acl = assertion
 failure: !asyncInProgress() in ~ACLChecklist

This patch allow an ACLList destroy itself after check is complete.

If there is asyncInProgress() when the request is being destroyed, then let acl
checklist destroy it self once the check is done.

Patch provided by Gonzalo Arana.
