/*!
 * This file is the "API" that implementations of RPCs or other code can use to submit things to the
 * ISO thread. Note that not all RPCs use this API - for example the DGO RPC just manually submits
 * messages.  Generally, these functions will not return until the actual action is complete, like a
 * file is loaded.
 * - except for messages to pause/play audio, those functions will return immediately, but there may
 * be a delay until they are actually processed.
