 // one payload item at a time.
 //
 // The key object will be stored twice, so it should support efficient copying.
 //
 // NOTE: While all operations are O(1), this code is written for
 // legibility rather than optimality. If future profiling identifies this as
 // a bottleneck, there is room for smaller values of 1 in the O(1). :]
