- 'dealloc()` must behave like C's `free()`, accepting either a
pointer returned from its allocation counterpart or the values
null/0 (for which it must be a no-op). allocating N bytes of
memory and returning its pointer. In Emscripten this is
null/0 (for which it must be a no-op). In Emscripten this is
conventionally made available via `Module['_free']`.
APIs which require allocation routines are explicitly documented as

ACHTUNG: calling this often, e.g. in a loop, can have a noticably
painful impact on performance. Rather than doing so, use
heapForSize() to fetch the heap object and assign directly to it
or use the heap's set() method.
