 * @note Doing some benchmarking indicates that the new operator is much
 | 
						|
 *       slower than the clone operator (even discounting the cost of the
 | 
						|
 *       constructor).  This class is for that optimization.
 | 
						|
 *       Other then that, there's not much point as we don't

 *       maintain parallel HTMLPurifier_Token hierarchies (the main reason why
 |

 *       you'd want to use an abstract factory).
