ObjectSpaces and MBF both delayed till Longhorn

First we learned that MBF has been delayed till Longhorn (from Tim Brookins) and now ObjectSpaces is adopting the same schedule. The official announcement is here.

I wonder if ObjectSpaces was delayed and that caused the MBF re-schedule, since MBF uses ObjectSpaces for persistence. Either way, because of the extra time, they'll both be stronger and more tightly integrated when they do get released.
