Comment:

 What's the motivation on this one?  And why 10 seconds?

 There's probably a better name than ConnStatistics here; lots of our other
 statistics could fairly be called connection statistics.
 ConnDirectionStats?  ConBidiStats?

 BIDI_THRESHOLD and BIDI_INTERVAL and BIDI_FACTOR are uncommented.

 Doing a round trip to disk here feels a little kludgy; it could probably
 use unit tests too.

 Looking at the code that generates the extrainfo, it looks like if we
 leave ConnStatistics on for a while, then turn if off for a year, then
 turn it on again, there could be a window when the old ConnStatistics from
 a year ago get written in the extrainfo.  Is that true?  If so, is that
 really what we want?

 In any case, it looks like a new feature; is there a good reason to add it
 to 0.2.2.x rather than waiting for 0.2.3.x?
