  If the GC'd language doesn't reorder elements in memory to be more
cache-friendly, that can have a rather large penalty in speed.

  The speed difference between cache-friendly and cache-unfriendly code
can be surprisingly large, even if both do the exact same thing otherwise.
We are talking about something of an order of magnitude slower at worst.
Cache misses are *very* expensive.
