  `You're wrong about the crumbs,' said the Mock Turtle:
`crumbs would all wash off in the sea.  But they HAVE their tails
in their mouths; and the reason is--' here the Mock Turtle
yawned and shut his eyes.--`Tell her about the reason and all
that,' he said to the Gryphon.

  `The reason is,' said the Gryphon, `that they WOULD go with
the lobsters to the dance.  So they got thrown out to sea.  So

   * underutilization. If, on the other hand, we pick a function that goes /above/ that horizontal
   * line, then it means that the area (time) is increased, thus storedPermits are more costly than
   * fresh permits, thus the RateLimiter becomes /slower/ after a period of underutilization.
