Module name:	cluster
Changes by:	pcaulfield at sourceware.org	2007-01-16 09:54:43

Modified files:
	cman/daemon    : commands.c 

Log message:
	Don't return to 'cman_tool leave' until we are just about to quit.
	Otherwise there can be a delay between cman_tool thinking that we
	are down, and the node really being out of the cluster.
	see bz#222686
