Just looked more carefully:

- the configure test you report does lots of exec(). A horrible lot of.
- the exec test tests exec speed, of course.
- the sh test might well depend on exec() speed a lot
- the dc test might also depend on exec() speed a lot, if it calls dc ot
  just execute one command, then executes it again in a loop.

So a cache problem, or just former cache-not-properly-handled problem, will
result in something like the observed performance hits.
