Marc-Andre proposed exactly the same thing back at the end of March (to
me and Guido). The two of us hashed out some of the stuff and M.A. came
up with a full patch for the stuff. Guido was relatively non-committal
at the point one way or another, but said they seemed fine. It appears
the stuff never made it into source control.

If Marc-Andre can resurface the final proposal/patch, then we'd be set.

Until then: use the bufferprocs :-)
