'service pacemaker stop' seems to take down cman as well, but frequently stalls 
before that.

we are definantly not taking down cman ahead of time.

But we are seeing problems on some systems where we start everything up, verify 
both nodes are seen, and then a day or so later notice that the two boxes are 
not communicating (one of the reasons we are looking at disabling multicast, the 
local networking people have 'interesting' ideas about multicast, and they may 
be causing problems)
