The fact that this tree is already a year old, and not likely to be
brought forward for at least another 2 years is the reason we didn't
choose it this time.  Most of the high-profile, active embedded projects
are already on 2.6.35.  For companies looking to adopt a new base kernel
in the next 12 months, I don't want to have them start with a year-old
kernel.  We did consider the utility of synchronizing with the enterprise
stable tree, but the timing just didn't work too well this time around.
