Oh, well! I thought we had a better story there :-(
Maybe the speed up I remember was linked to the rework I suggested back
then to work around the poor lexical-scoping performance (mainly moving
a condition-case outside of a loop, IIRC) and that actually improved
performance with both lexical and dynamic binding?
