[snmp] snmpv3 context receiver thread destoyed

[Josh Bers]

Birgit and Tim,
 
I believe that the problem I am seeing is compounded by the long timeouts
enforced by the UsmDiscoveryBean ~20 seconds..
 
say I am polling for data every 5 seconds, but the device is down so the
discovery bean retries 4 times at 2 4 8  seconds
 
that means that i'll have a backlog of USmDiscoveryBean requests outstanding
when one finally, goes through..and then another..
How does the stack respond to multiple USM discovery requests comming back
from the same snmp agent?
