Summary:                    AMI Action: Queuestatus + asterisk -rx "queue show"
= no more calls sent to agents
Description: 
If an outside application sends AMI Action: Queuestatus and at the same
time asterisk -rx "queue show" is run, calls are no longer sent to agents.
With loglevel 3, the message

[Apr 21 15:28:58] ERROR[18863] utils.c: write() returned error: Broken
pipe

is logged (typically) equal to the number of lines of output that would
typically be sent as a result for the AMI Queuestatus.

'agent show online' will show the agents as idle, and 'show channels
verbose' shows new incoming calls in Application Queue.

Testing with less aggressive timeouts and eliminating network between hosts
produced the same results. Test scripts used:

queue-showloop.sh:
-----------------------
#!/bin/bash
x=0
while [ $x -lt 5000 ]
 do
        echo $x
        x=$[$x+1]
        asterisk -rx "queue show" | grep strat | grep default

        sleep 5
 done
-----------------------

ami-holdopen.sh:
-----------------------
#!/bin/sh

echo "open $1 5038"
sleep 1
echo "Action: Login"
echo "UserName: ami_peer"
echo "Secret: tester01"
echo
echo "Action: QueueStatus"
echo
sleep 1000
echo "Action: Logoff"
echo
sleep 1
-----------------------

(run using:)
./ami-holdopen.sh 127.0.0.1 | telnet > test-050311
