   * Note well that if, for this function, we chose a horizontal line, at height of exactly (1/QPS),
   * then the effect of the function is non-existent: we serve storedPermits at exactly the same
   * cost as fresh ones (1/QPS is the cost for each). We use this trick later.
   *
   * If we pick a function that goes /below/ that horizontal line, it means that we reduce the area

Esta "espera" 🕙 se mide en microsegundos, pero aun así, sumando todo, al final es mucha espera.

Es por eso que tiene mucho sentido usar código asíncrono ⏸🔀⏯ para las API web.
