Subject: [PATCH] Add some initial memory tests

These can be executed using valgrind --tool=massif to get a rough idea of
memory behavior.  Valgrind massif using libc allocation primitives does
carry overhead that a proper pool allocator doesn't (they can be made
overhead free); but these numbers are still useful as guides.
