d) We havn't tested it fully in our QA process, nor has it been
available long enough for us to feel comfortable turning it on at this
stage.  We also would need to invesgate how to do it in our universal
binaries, etc.  Its a lot of testing and it unfortunately will not make
2.0 unless there is a compelling argument against this and support from
the runtime team and from the QA team.
