Server Differences

TinyMUX is the only server to support this function. However, add() is equilvalent for numbers up to just under 2^53 or 9007199254740977. Also, add() on a typical machine takes about 44 us versus iadd() taking 2.8 us on the same machine -- or, about 16 times slower. For smaller numbers, add() special-cases to an integer code path and takes about 3.1 us -- or, only 10% slower.
