Last change on this file since 6c81223 was 6c81223, checked in by Alejandro R. Sedeño <asedeno@mit.edu>, 12 years ago
Fix _followlast behavior. I broke _followlast in 26255f0a891e35ce73aef0db49ff403c3d69efeb. This restores that functionality by checking to see if we should followlast /before/ processing messages off of the message queue.
