-"""Small extension altering some push behavior
-
-- Add a new wire protocol command to exchange obsolescence markers. Sending the
-  raw file as a binary instead of using pushkey hack.
-- Add a "push done" notification
-- Push obsolescence marker before anything else (This works around the lack
-of global transaction)
