This is a general issue I think. I hope for the 1.4.0 beta to go through all 
the plugins and reset the default timeout to be a few seconds greater than 
the critical time interval. We still should be able to set the timeout 
explicitly, if you want to let a subsystem use it's own clean closing, but 
the default should not have ping timeout after 10 secs if -c is 2 secs.
