CVSROOT:	/cvs/cluster
Module name:	cluster
Branch: 	RHEL5
Changes by:	pcaulfield at sourceware.org	2006-12-12 16:51:11

Modified files:
	cman/cman_tool : join.c 

Log message:
	Fix minor bug where cman_tool join didn't spot that aisexec had started
	correctly or crashed.
	
	This means we can up the timer for allowing aisexec to start with no ill
	effects. see bz#218688
