Yet another reason why the mlprof numbers are unbelievable.  Consider
a self-compile.  Here are some extremely conservative upper bounds.

* number of gcs: 10E2
* number of MLTON_gc copy statements per gc: 10E4

Hence, an upper bound on the total number of copy statements is 10E6.
mlprof claims this is taking 71.82% * 303 = 217 seconds, i.e. 2
milliseconds per assignment statement.
