I'm not sure about that one without figuring out *why* it's taking so
much time.

If you're re-using the response PDU to create a new PDU then that will
be problematic and you shouldn't free it.  If you've put in static
data into the initial PDU that wasn't allocated in the first place,
you'll run into similar problems since snmp_free_pdu will try to free it...
