The new memory manager actually wastes less memory than the old one, scales
better and most important to this discussion, the memory consumption is far
more accurate as it also takes into account the memory manager overhead.
Therefore, we are not consuming 1.5x memory, but we are reporting a more
accurate number which is about 1.5x of what the old one reported.
My suggestion is to raise the limit to 16M both in the php.ini* files that
come with PHP and in the source.
