GMS: graceful leave takes a long time
-------------------------------------

                 Key: JGRP-842
                 URL: https://jira.jboss.org/jira/browse/JGRP-842
             Project: JGroups
          Issue Type: Bug
            Reporter: Bela Ban
            Assignee: Bela Ban
             Fix For: 2.7


Scenario: 
- A and B
- B leaves gracefully
- A leaves gracefully
- It takes A GMS.leave_timeout ms to leave where the leave should be immediate

Reason: we get a SUSPECT(B) event on A (see https://jira.jboss.org/jira/browse/JGRP-841) although B leaves gracfully. The GMS.ViewHandler has now a SUSPECT event in the queue, and we cannot leave until this event has been processed.

SOLUTION:
- Fix JGRP-841
- Take a look at Channel.disconnect() and close(). Both call stopStack() regardless of whether it has already been called. This invoked stop() in all protocols, and GMS calls ViewHandler.stop(). This method doesn't check whether stop() has already been closed and adds a flush marked to the queue.

This does not occur in the 2.6 branch.
