There are tons of incredibly useful features in Bro. Its always interesting
to see the research papers those features came from. I'm referring to table
expiring attributes in this case.

Its also interesting to read that connection timers are only disabled at
connection state removal. Are they periodically removed similar to hash
table resizing in figure 3? In any case, it's smart that their removal
comes second to packet processing.
