glib/gio/gvolumemonitor.c
Dan Winship 65cc5d895a Support g_main_context_push_thread_default() in gio 
GFile allows for the possibility that external implementations may not
support thread-default contexts yet, via
g_file_supports_thread_contexts(). GVolumeMonitor is not yet
thread-default-context aware.

Add a test program to verify that basic gio async ops work correctly
in non-default contexts.
