new protocol:
Master either says
  << hello
or
  << idle $N
if the slave should retry later.
The slave is still allowed to continue communication, e.g. to submit
logs. If the slave wants to continue:
  >> arch $ARCH
(at this point the master fetches Packages file and loads the db)
  << ok
(or "error" if arch is wrong without opening the db, closes the connection)
(or closes connection if something happened while initializing the db)

continue as usual
