Yup - almost 2.5 times faster on the large benchmarks in the Benchmarks
package off SM. No change in bytecodes/sec since that isn't affected by
changes in prim calling, and a small improvement in the sends/sec test
for similar reasons. But if your time() like calls cost anything
noticeable and you're doing it up to three times for every prim
(including simple arithmetic & atputs) it adds up fast.

I'm still pretty sure that send/return could be several times faster
with work but I'm not about to start spending that sort of time unless
somebody pays.
