Comment (by arma):

 See my feature9574 branch for some dabbling.

 It's based on maint-0.2.4, on the theory that we are increasingly
 realizing that the hypothetical DoS attack from this ticket is occurring
 right now via our botnet, and it's growing increasingly urgent to rescue
 our relays from CPU overload.

 The branch doesn't have a changes file, could use some more refactoring,
 and it leaks everything at the end of the unit tests; but hopefully it is
 useful for somebody working on this ticket.

 I'm running it on moria5 right now.
