Nevertheless, I've seen attempts to patch single-threaded code into
multi-processor code go into the weeds a hell of a lot faster and a hell of
a lot more frequently than attempts to engineer proper multithreaded data
structures from the start.  The difference between a single-threaded system
and a multi-processor system is *not* just missing code.
