**********************
A fair bit of simplicity is created by creating small functions for simple
tasks, even when the function is only called in one place. This may
measurably slow things down [or may not] by creating more function call
overhead than is necessary. The source is laid out so that it's trivial
to make the affected functions inline so that one can measure what speed
up, if any, can be achieved, and maybe later when things settle things can
be rearranged.
Help stamp out big monolithic functions! */
