// This function performs the low-overhead signal handler initialization that we
// want to do eagerly to ensure a more-deterministic global process state. This
// is especially relevant for signal handlers since handler ordering depends on
// installation order: the wasm signal handler must run *before* the other crash
// handlers and since POSIX signal handlers work LIFO, this function needs to be
// called at the end of the startup process, after other handlers have been
// installed. This function can thus be called multiple times, having no effect
// after the first call.
