AFAICT, my problem happens with equal frequency for all keys.

The problem isn't that a key produces the wrong result. The
problem is that sometimes a key will be "missed" and sometimes
a key will "stick" until another key is pressed. It only seems
to happen under heavy load (e.g. when compiling programs), and
it's now happening on multiple machines.
