According to AddressSanitizer, when `sandbox_malloc` causes the WebAssembly memory to grow in size, every single coroutine on the sandbox stack gets corrupted. So if `sandbox_malloc` is going to cause the memory to grow in size, we need to yield so that there are no coroutines on the sandbox stack while the reallocation occurs.
