Could we enable mtrace directly via LD_PRELOAD (or static linking),
without calling the function?

There's also the matter of not flagging potentially leaking allocations
from the test harness itself.

I don't have a strong preference.  Given the open questions, it's
probably best to delay the cleanup.

Thanks,
