"""
Concurrent queries
++++++++++++++++++
Send multiple SNMP GET requests at once using the following options:
* with SNMPv2c, community 'public'
* over IPv4/UDP
* to multiple Agents at demo.snmplabs.com
* for instance of SNMPv2-MIB::sysDescr.0 MIB object
* based on asyncio I/O framework
Functionally similar to:
| $ snmpget -v2c -c public demo.snmplabs.com:1161 SNMPv2-MIB::sysDescr.0
| $ snmpget -v2c -c public demo.snmplabs.com:2161 SNMPv2-MIB::sysDescr.0
| $ snmpget -v2c -c public demo.snmplabs.com:3161 SNMPv2-MIB::sysDescr.0
