 Note that we should still fix the IRC analyzer. The signatures should just
 be a hint for the analyzer (to speed things up) and that the analyzer can
 detect whether it's parsing the right protocol. Without resource
 constraint, DPD could/would run all analyzers on all connections and then
 analyzers and if an analyzer can't parse the connection it detaches from
 the tree.

 (Not changing ticket status yet, since YMMV)
