Someone reading unrelated code would have to check what these helpers are about with the current naming, with an 'idle' in the name, it's much easier to guess what they are about and decide not to care about the details. > +void g_task_helper_return_int(GTask *task, > + gint integer); g_task_return_int takes a gssize, not a gint.
