JOIN_RSP should interrupt thread blocking down on findInitialMembers
--------------------------------------------------------------------
Key: JGRP-621
URL: http://jira.jboss.com/jira/browse/JGRP-621
Project: JGroups
Issue Type: Bug
Affects Versions: 2.6
Reporter: Vladimir Blagojevic
Assigned To: Vladimir Blagojevic
When clients attempts to join it loops through:
while(!joined){
fetch the initial members
determine coordinator
send join request to coordinator
wait for join response (timeout)
if(joinok)
joined = installView
}
Unlucky timing of join response arrival can delay successful view installation and lead to
unforeseen problems. If waiting for join response timeouts then joining thread repeats a
loop and sends a blocking request to fetch initial members again. If response arrives
while joining thread is fetching for the initial members then joining thread has to wait
for fetching of the initial members to return in order to proceed with view installation.
Fix for this issue should ensure that If successful join response arrives then joining
thread should be interrupted and proceed with view installation immediately.

Vladimir Blagojevic commented on JGRP-621:
------------------------------------------
This bug is sometimes cause of gms failure to collect all ACKs [1] under flush since flush
waits for all members to ack view including new member. In this case new member is blocked
in fetch the initial members phase for too long to send a response during
view_ack_collection_timeout.
[1] GMS: - failed to collect all ACKs (4) for view [127.0.0.1:7800|3] .......

------------------------------------------
In the worst case view installation will be delayed for timeout specified in PING
protocol. Default for TCP was 3 seconds ,bigger than default view_ack_collection_timeout.

Further issues to solve:

which is only set
on reception of JOIN-RSP
- We do not interrupt the sleep() in join_retry_timeout even when we get the JOIN-RSP

Fixed by having the join() call create a Promise, and pass the Promise down to Discovery.
Discovery then returns when
