Yup, I think I've noticed that as well ... No more wrapper leaking, but
DateTime still seems high, and the request related classes still grow.

I don't use Plone however, just standard CMF.

Right now I'm trying out recipe 14.10 from the Python Cookbook: Tracking
Instances of Particular Classes.

Hopefully with the ability to "attach" to instances left around through the
monitor I can inspect them and find out what's so special about them :)

No eureka moment from me yet! :P

Interesting - I applied LeakBGone to zope.org, and while it 
did not fix the problem, it did seem to change it in an 
interesting way.

Before, there were far more ImplicitAcquirerWrappers than 
anything else. Now, I'm consistently seeing ~100,000 DateTimes 
and ~36,000 PloneFolders after running for about 90 min., and 
the wrappers stay stable at around 250.

Not a clue what it means yet, but I thought I'd share another data 
point in case it makes someone say "eureka"...
