I think the time gained in unnecessary instanciation/garbage collecting
will more than offset the synchronized code, and it will contribute to
reduce the memory footprint of the system, thus perhaps avoiding swapping
on some systems. On high end systems, this won't have a great impact, but
on the lower end I think this will provide a significant improvement.
