2.6.4 is obsolete and unsupported

Zope 2.6.4 has the same problem. The fix should be backported there as well.

I am not sure how many people are having problems with
this leak. If there is a significant evidence that this
patch solves the leaks of several people, I will think about a 2.7.3 release.

This leak is generally triggered by a security check on a protected value in the context of an object with empty proxy roles (e.g. Script (Python), DTMLMethod). Symptoms are increasing refcounts for ImplicitAcquirerWrapper and HTTPRequest/Response.
Supplied patch is against SVN Zope HEAD but applies to Zope 2.7 as well. I can provide a separate patch for Zope 2.7 if needed.
