I don't know if it's reclaimed or not, but I think it should be
reclaimable.  And if the GC reclaims it, next time around the loop the
same (now free) cons-cell should be reused instead of requesting more
memory from the OS.

So according to how I expect the code to behave, this setting might
cause the memory footprint to be (very slightly) larger but it should not
cause it to keep growing.
