Actually that is only the delay for the debug output blinkenlights. The
extraction process reads words (samples the current value) from the
entropy source whenever a command is received and is thus related to the
speed of the serial interface. Right now that is either 9600 or 256k.
Still way below one per cycle @ 50 MHz.
