*If* Bro expires a UDP connection, it raises
connection_state_remove. But you're right, but default Bro doesn't
remove (most of the) UDP state. But you can set a
udp_inactivity_timeout, then it will (in fact, if you're analyzining
UDP traffic you *really* want to have such a timeout; otherwise your
table is probably the smallest problem :-)
