Hi,
*preliminary* patch attached. This needs a good bit of polishing
(primarily comment work, verifying that valgrind works), but I'm too
tired now.
I'm not quite sure how to deal with mmgr/README - it's written as kind
of a historical document, and the "Mechanisms to Allow Multiple Types of
Contexts" is already quite out of date. I think it'd be good to rip out
all the historical references and just describe the current state, but
I'm not really enthusiastic about tackling that :/

Included.
With Craig's help I've verified that the patch as attached works on a
platform that's currently failing. Thanks!
