Wow, that works like a charm. Blender memory use may have increased a
bit though, but I'm not sure. Gotta check that later, will finish my
bake now first. No more stalls between the simulation frames.

>From reading into tcmalloc, it has options to release the unused memory
to the operating system, so that's something which could be called after
a full bake or alike. Otherwise, tcmalloc seems to be releasing memory
gradually[1] (similar to what the memory manager of sun java does).

Thanks for pointing that out,
