Ho ho hum, merry christmas, gift attached.

I'll beat on virgin -rt7, see if it survives, then re-apply RCU patch
and retest.  This kernel had nohz_full enabled, along with Sebastian's
pending -rt fix for same, so RCU patch was not only not running solo,
box was running a known somewhat buggy config as well.  Box was doing
endless tbench 64 when it started stalling fwiw.
