When your Zope comes back again (i.e. stops iterating finally),
you can use my ZopeProfiler

to learn what is using time (not memory!) in your Zope instance.

Its written after the request. Only then, the response code and
Content-Length is known.

No, as memory consumption is not attributed to a thread (and
therefore a request).
