* dbus/dbus-mainloop.c (_dbus_loop_iterate): fix logic so that if
	there was an OOM watch we skipped, we always return TRUE so we

	Code rearrangement also lets us lose some memset and only iterate
	over callbacks once.

	* bus/driver.c (bus_driver_handle_message): sense of test for
	reply was backward
