* Source/NSData.m: ([setLength:]) increase size of buffer in chunks
proportional to the current size ... so if we add small amounts to a
buffer many, many times, we don't reallocate the memory for each tiny
increment. Should make accumulating large amounts of data into a
buffer much more efficient.
