The document is available at


There are several topics covered. Ideally, I would prefer that we discuss
each topic separately. The main ones I will start working on are the ones
described in the bugzilla links we have in the doc.

This is just a starting point for us. I am not at all concerned with
implementing exactly what is proposed in the document. In fact, if we can
get the same value using the existing support, all the better.

OTOH, any other ideas that folks may have that work better than this are
more than welcome. I don't have really strong opinions on the matter. I am
fine with whatever works.

Thanks.  Diego.
