Comment(by arma):

 Replying to [ticket:5380 arma]:
 > So if the Tor client stays running for more than a month or two, its
 guard behavior deviates from normal.

 Actually, it's worse: if the client stays running for a week, and it would
 have dropped its old guard on day 1 of that week, it doesn't. This turns
 things into a subtle statistical attack (which still seems bad).
