 * milestone:  Tor: 0.2.5.x-final => Tor: 0.2.???


Comment:

 For strftime, I think the only likely cause of failures is output too
 large for the buffer, and it's too big a refactor to check the returns in
 0.2.5.  I'm sending this to 0.2.?? for now, and at some point we should do
 one of the following:

 1.) Refactor so we can check strftime() returns

 or

 2.) Audit each call and be sure the buffer is always large enough, and
 then decide that suffices and close this.
