/**
 * selenium-standalone is limited to how many parallel calls it can handle. A call such as

 * reset" errors. (See also https://github.com/SeleniumHQ/selenium/issues/5611)
 *
 * This file implements throttling of calls, to ensure that at most maxPendingCalls are
 * outstanding at any given time. It can be applied to any promise-returning method.
