[Zope] Leaking ZClasses.Method.MWp

[ezCompany Internet Technology]

Hi All,

It looks like my Zope instance (2.7.2, patched cAccescontrol) is leaking 
ZClasses.Method.MWp classes

Acquisition.ImplicitAcquirerWrapper 2047 100751 +98704
ZClasses.Method.MWp 8544 34185 +25641

I can't figure out where this class is used in my application. I even 
can't find where this class is located in the zope sourcecode.

Greetings Ralph
