Out of curiousity --- do you folks still have plans to provide precise
GC, or have you gotten comfortable enough with the Boehm collector
that you don't feel it's worth the trouble any more?  There's been
enough hard work put into the Boehm GC that it would probably take a
while for a freshly written precise collector to catch up, in both
performance and stability.

The last note I could find on this question was Dietmar Maurer's:

But then Paolo Molaro's slides about "Hosting the Mono Runtime" are a
bit more equivocal:


    * Will require API changes if we ever use a precise GC

Them's some big API changes.  Seems like it would be good to settle
the issue early.
