I already removed the use of the "format" egg (the code contains a
commented-out version that relies only on "display"), and even
completely disable the println call.  It's hard to be sure, but it
*looks* like the majority of the time is being spent in the division
procedures.

Seeing how it fares on other Schemes would be interesting though!
