/*
 * Combine multiple calls to run (e.g. session.request) into minimal number of group calls.
 * All calls to run will be remembered and executed at once at the next macrotask
 * (i.e. after all already resolved promises/async functions are executed).
 * commandRunner must be a function that accepts an array of arguments (commands)
 * and returns an array of results (possibly promises) of the same length.
 * It's intented to use a wrapper around session.execute as a commandRunner.
