Summary:                    Queue with autofill=no and strategy=ringall
sometimes rings non-oldest caller through to agents
Description: 
I'm experiencing a possible bug in 1.4.26 x86_64 with app_queue.  I have a
queue set to strategy=ringall and autofill=no, but I am seeing autofill
behavior (non FIFO), with latter callers ringing through before the oldest
caller has been answered.

Example: A caller sits on hold for 2 minutes (due to all agents being
busy), then a new caller enters the queue.  An agent becomes free, and as
it happens, the newer caller (with a shorter hold time) rings through to
the agent and the call is answered, leaving the caller with the longest
hold time still unserviced.

Reviewing the logs, it's clear that asterisk is correctly retrying to send
the oldest caller through at the correct interval.  It just looks like the
newer caller seems to have squeezed through, and happened to be answered
first.

My queue definition is listed in 'Additional Information'
