Brilliant!

> that the array was getting cloned

I think it's not so much the copying alone but the allocation of a new array each time.

Because the arrays are growing, old released memory often can't be reused, leading to a fragmentation and increasing waste of space.

Fun! :)

Tho I might be wrong, the reserved space for an array grows by doubling IIRC, this should be easier to reuse ...
