My apologies, I accidentally typed "mint" instead of mini, which led
me to mis-speak.  Let me re-state: "mint core-dumps trying to run the
program". I know mint has some issues, is it going to be working again
someday, or is it going to die in favor of encouraging people to port
mini?

The output is below to avoid further confusion. While this is hardly
rigorous enough to draw conclusions, it's interesting that the MCS
compiled program has faster times for index_test, index_string_test,
and nested_test, independent of the JIT it's run on.
