Following up Herbert's question, I wrote:<br>

So, some obvious questions:<br>
- in the interpreter vm, why is comparing two floats slower that an
integer and a float?<br>
- what's up with Cog? Three tests are faster by the expected ratio
and one took a real dive.<br>
<br>
Also, the profiler Herbert used could use some attention to the
NewFloat printing:<br>
