The SnmpEventLoop class provides an EventLoop to all the MIB modules that need to communicate with XORP. The modules will use the EventLoop to instanciate listeners required for asyncronous inter-process communication with XORP.

| SnmpEventLoop& the_instance ()
| the_instance |
[static]
This function provides the only way to instantiate this class, since all other constructors are private. Use it like this:
SnmpEventLoop& e = SnmpEventLoop::the_instance();
Now use 'e' anywhere you would use an event loop in Xorp modules, for instance:
XorpTimer xt = e.new_periodic(100, callback);
NOTE: typically you would never need to call e.run(). If you do, you should set a short timeout, since while your MIB module is blocked, you cannot process any other SNMP requests.
Returns: reference to the SnmpEventLoop used by all XORP MIB modules.

This is the name this class will use to identify itself in the snmpd log. Only used for debugging
