> Memory checking tools like valgrind can't give much help when we use a custom allocator.
> Make it possible to build dispatch using malloc/free instead so it can be checked with valgrind.
> This is not the ideal solution. It tests the code that uses the allocator but does not test the allocator itself.
> A better solution is to instrument the allocator for valgrind use, see:
> http://www.valgrind.org/docs/manual/mc-manual.html#mc-manual.mempools
> However this is more complex and doesn't help with other memory debugging tools. Disabling pools at build time is a useful first step. It also lets us test performance of the pool allocator against plain malloc. A full valgrind integration with pool allocation is a possible future exercise.
