[MIT-Scheme-devel] Bottlenecks

              (fluid-let ((*dead-registers* dead-registers)
                          (*registers-to-delete* dead-registers)
                          (*prefix-instructions* (LAP))
                          (*suffix-instructions* (LAP))
                          (*needed-registers* '()))

Fluid-let seems to be rather expensive, and this one is called a lot.
