One way around this is to allocate in slabs


Right, but you're still allocating. Initially I didn't realize the issue was strictly fragmentation. My TTF rasterizer already uses a custom pool/heap for allocations.

If the memory manager uses buddy allocation and you allocate temporary memory and then free it all before allocating more, fragmentation should be avoided altogether.


Typically I allocate for the span of an operation in order to improve performance. Sometimes I fallback to a slower method if I can't allocate, so it gets used like a cache. It gets freed once the operation completes.

This is the case in every situation in my graphics library save a couple of very explicit things like "large bitmaps" which are actually composed of a bunch of smaller bitmaps because of heap fragmentation, and things like SVG documents (which are actually kind of small).
