The speed improvements associated with these MFC's is minor; primarily they
are stability improvements under high load. There are major performance
improvements in the 7.x implementation, especially for multi-core systems, but
I have no current plans to MFC them, as they interact with other system
components and may depend on other changes that also haven't been MFC'd.
