Remember, there is a cost to having more variables GCed, and a cost to
compacting memory. The most efficient solution might not be to GC
every variable and compact memory every time.
The cost of GCing a single small structure is not noticeable; but a
large array with many pointers is more expensive, and lots of little
structures is expensive.
