    gmain: repeat preconditions for emphasis
    
    g_main_context_acquire() mentions that you must have called it before
    you make any calls to _prepare(), _query(), _check() or _dispatch().
    
    For emphasis, add a note on each of those functions pointing back to the
    fact that you must have called _acquire() before using them.
