 In [http://archives.seul.org/tor/dev/Mar-2015/msg00197.html my analysis of
 Tor's callgraph] , I found that a lot of our callgraph's complexity comes
 from the fact that all the code that generates a controller event can try
 to call into the network stack.  And since controller events can come from
 nearly anywhere in the code, that's quite a problem for modularity.

 So, let's try to make the "blob" smaller by decoupling the logic here.
