// General approach here:
// * Maintain a queue as an array of objects containing key-value
// pairs. Putting values into the queue will assign to the
// earliest-available queue position for the associated key
// (appending to the array if necessary.)
// * Maintain a set of counts for each key, such that determining
// the next available queue position is easy; O(1) insertion.
// * When retrieving objects, pop off the queue and decrement
// counts. This provides O(n+k) or O(k) retrieval for a queue
// of length n with k unique keys; this depends on whether
// the browser's implementation of Array.prototype.shift is
// O(n) or O(1).
// Graphically (indexes at top, keys along side, values as *'s),
// if we have a queue that looks like:
// 0 1 2 3 4
// a * * * * *
// b * *
// c * * *
