+
+ * giomodule.c:
+ Make g_io_modules_load_all_in_directory not unuse
+ loaded modules so that users of it can do stuff
+ before unloading.
+ Init internal "module" types.
+ Initialize static prio and name for types so that
+ we don't have to load modules to get it.
+
+ * gnativevolumemonitor.h:
+ * gvolumemonitor.h:
+ Move is_supported to parent class so that
+ non-native monitors can avoid being initialized
+ too. (For instance GDaemonVolumeMonitor if we're
+ not using GDaemonVfs.)
+
+ * glocaldirectorymonitor.[ch]:
+ * glocalfilemonitor.[ch]:
+ * gunionvolumemonitor.c:
+ * gunixvolumemonitor.c:
+ * gvfs.c:
+ Find plugins using the static prio+name to
+ avoid unnecessarily loading the modules.
