I thought that -timeout was per-test, but it is for the
whole program execution, so cmd/go can adjust its timer
(also for whole program execution) accordingly.

If the values being compared have different concrete types,
then they're clearly unequal without needing to invoke the
actual interface compare routine.  This speeds tests for
specific values, like if err == io.EOF, by about 3x.
