Comment (by robgjansen):

 This is for the upload to server variant of the sniper attack. For each
 exit stream at the exit relay, track a LastReadTimestamp - the last time
 that stream was read from by the destination. Then, while the OOM killer
 is checking all circuits for the one with the oldest cell, have it also
 consider the exit streams' LastReadTimestamps and kill the oldest
 circuit/stream accordingly.

 What breaks here?
