Deadlock with concurrent stack in FC if RPC response blocks
-----------------------------------------------------------

                 Key: JGRP-928
                 URL: https://jira.jboss.org/jira/browse/JGRP-928
             Project: JGroups
          Issue Type: Bug
    Affects Versions: 2.6.8
            Reporter: Brian Stansberry
            Assignee: Bela Ban
             Fix For: 2.6.9

JGroups 2.4 and earlier had a deadlock problem in FC if a thread carrying an RPC came back down the stack with a response and blocked for credits.  This was fixed with JGRP-465.  But with the concurrent stack that fix has broken; needs to be reinstated.  The variable that tracks upgoing threads needs to be converted from a ref to a Thread to a Set<Thread>.
