Have you considered using a more general purpose solution like tcmalloc or jemalloc?

FWIW, on a side note, jemalloc required defining EIGEN_MALLOC_ALREADY_ALIGNED to 0 the last time I tried it because its allocator didn't guarantee always 16-byte aligned pointers. For really small allocations, it can return 8-byte aligned pointers.
