Stretchy arrays (Re: Efficient coding considered harmful?)

[Steven Ryan]

The problem is that allocating by some multiple badly approximates the required
size after a number of iterations.

Getting back to the original point: Make sure the basic algorithm is good.

(1) Can you never have the case where the next realloc will require more
    memory than available even though the actual size needed will fit?

(2) Can you avoid storage fragmentation so that only the current allocation
    exists and not all previous incarnations?
