Two overnight tests passed here with this stack (octa-core xu4q/armv7
and quad-core x86 SoM), running loops of the condvar app you sent me,
and the EVL test suite in parallel. Although we may not be done yet,
this is a positive outcome given the amount of stress these tests impose
on the EVL core.

However, the evl ps display you sent me, showing a PI boost would
require some investigation if these threads would never switch back to
their normal priority, clearing the 'b' flag accordingly in the STAT
field.
