/*
These settings are for WASM build. In WASM, memory is allocated in "pages",
where each page is 64kB. For efficiency, this build of Microvium assumes that
we're only using the first page of memory, so it's similar to having an MCU with
64kB of RAM. But this does mean that an application can't really exceed about
32kB of RAM, since during a GC collection, the memory is copied (as in a
semi-space collector).

This WASM library will use 2 pages in total: the first page is the RAM, and the
second page is the "flash" memory, for the snapshot.

Since memory is pre-allocated in WASM, and can only go up in pages, this means
that WASM Microvium will only use exactly 2 pages of memory - no more and no
less.
