[m-dev.] Upgrading Boehm GC, attempt #2

[Paul Bone]

Hi,

YesLogic would like us to upgrade BoehmGC.  I'm going to review my work and
any issues that people raised last time I posted this, address them and then
attempt to merge this old branch into master.  I won't commit the merge
until next Monday.

I will be away Thursday-Sunday this week so I'm holding off on committing
this until Monday, when I can help to deal with the aftermath.

Cheers.
