Just to clarify here, "Apple" release have nothing to do with llvm.org releases.  The LLVM.org schedule is purely time-driven (a ~6 month cycle), and done by volunteers - including the @apple.com people who contribute to the releases.

The Apple schedule is quite variable, and often a lot more frequent than every 6 months.  This is why Apple release have always been based off a random revision number, usually irritatingly right in the middle of an llvm.org release.

This is just one more reason that it is important to me for the trunk to remain stable.
