Testing with WebKit reveals a difference so minimal that it's
not worth it. Same thing for switching to Stacks. So many
other things are going on that the gains in the Queue
processing are insignificant as part of the whole.
Consign this experiment to the 'interesting, but purely
academic" pile. However, it does illustrate that many
optimizations can be done without changing the
interface or the behaviour of a class.
