After reading about bufferevents in the v0.2.3.25 release notes I added "--enable-bufferevents" to my Tor config. Now I intermittently get this error: [warn] Bug: Duplicate call to connection_mark_for_close at directory.c:3571 (first at directory.c:3571) By "intermittently" I mean I've gotten this error 19 times in the past 11 hours, logged in groups of 2 - 6 at a time. No errors of this type are seen with v0.2.3.25 when not configuring for bufferevents. Are bufferevents supposed to be ready for prime time, or is this still a feature in development? **Trac**: **Username**: tmpname0901
