Subject: 2003-03-13  Havoc Pennington  <hp@redhat.com>

	* dbus/dbus-timeout.c (_dbus_timeout_list_set_functions): handle
	out of memory

	* dbus/dbus-watch.c (_dbus_watch_list_set_functions): handle out
	of memory

	* dbus/dbus-connection.h: Make AddWatchFunction and
	AddTimeoutFunction return a bool so they can fail on out-of-memory

	* bus/bus.c (bus_context_new): set up timeout handlers

	* bus/connection.c (bus_connections_setup_connection): set up
	timeout handlers

	* glib/dbus-gmain.c: adapt to the fact that set_functions stuff
	can fail

	* bus/bus.c (bus_context_new): adapt to changes

	* bus/connection.c: adapt to changes

	* test/watch.c: adapt to DBusWatch changes

	* bus/dispatch.c (bus_dispatch_test): started adding this but
	didn't finish
