2018-06-04	Openmp blocktime 1->20ms to keep cores enabled	Mika Raento
	With 1ms blocktime the benchmark app shows 3x performance degradation on Pixel 2 in float benchmarks (against no blocktime setting). In testing, 10ms was enough to give results comparable to no setting. 20ms was chosen as to have a 2x margin of safety while not keeping the threads busywaiting unnecessarily long.

2018-05-11	Reduce OpenMP thread busywait time (200 to 1 ms)	Mika Raento
	Reduce the time OpenMP threads used by Eigen busywait for new work after completing a piece. This is 200ms by default, which meant that we tried to continuously run 8 threads for 200ms after completing operations using Eigen - starving both our other work and the rest of the system.
