I hope to get to it this afternoon!  I especially like
the lockless nature of JRCU, and that the dedicated cpus
are not loaded down with callback inovcations either.
Not sure how to support the PREEMPT_RCU mode though; so
if Fredrick is planning to support that, that alone would
make his approach the very best.
