 9//   - The instruction list is too long to enumerate in godoc.
10//     See https://github.com/WebAssembly/threads/blob/main/proposals/threads/Overview.md
11//   - Atomic operations are guest-only until api.Memory or otherwise expose them to host functions.
12//   - On systems without mmap available, the memory will pre-allocate to the maximum size. Many
13//     binaries will use a theroetical maximum like 4GB, so if using such a binary on a system
14//     without mmap, consider editing the binary to reduce the max size setting of memory.
