Yup.

There's an event loop listening for incoming requests
on a list of sockets. This handles tasks 1, 2 and 4 in
your list.
Sending traps is either done as part of processing
SNMP requests, or using an alarm-based mechanism.

An alarm call will interrupt the normal event loop
processing, so if this happens too frequently, it might
well interfere with the prompt processing of requests.
I'm not totally sure what you mean by a burst of traps.
How would such a burst be triggered?
