	* tests/gio-test.c (shutdown_source): New function, that calls
	g_source_remove(). Check return value of g_source_remove(), and
	decrement running subprocess counter only if g_source_remove()
	actually did remove the source.

	(recv_message): Call shutdown_source() on EOF condition. Return
	FALSE on G_IO_HUP and G_IO_ERR condition. Fix printf format typo.
