Setting Framerate_Hz while grabbing only thinned out what the SDK handed over;
the camera went on sending 10 fps (and 50 from power-up). Set while the grab
is stopped, once the stream has run, it holds. So the grab is restarted with
the rate set when the first frame is in, and the packet rate of the camera's
port is counted: if it still carries more than 1.5x the rate's frames, the
restart is repeated (up to three times). On tower 111: 5.3 fps, 2 224 packets
a second instead of 22 234, on the second attempt; system load 18 % down from
about 29 %.
