Yes, that's known. The  piece of code that  did that had a  tendency to keep
using memory  until you killed  the qrunner. Barry did  not include it  as a
result (Ben is working on rewriting that piece of code in a way that doesn't
keep eating memory)
It is however possible to add the  code back from the original updated patch
I posted and restart qrunner nightly to free up the memory.

nodupes is a per end user feature (enabled by default for new users).  It is
true that if  you forge a Cc in an  Email before you send it to  the MLM, it
will cause that end user to not receive a list ocpy.

1) There isn't much that can be done about that.
2) It will not be an issue in most cases
3) end users worried by this can definitely turn nodupes off
   (and do deduping with procmail or some such)

nodupes was a  feature already present in  a few advanced MLMs  and at least
Ben and I saw it as a much needed feature for mailman
