class_docstr: Basic L{Linker} subclass that calls the perform method on each L{Op} in
  the L{FunctionGraph} in the order given by L{Linker.schedule}.
docstr: Parameters
  ----------
  fgraph
      A PerformLinker can have accepted one FunctionGraph instance at a time.
  no_recycling
      WRITEME
  
  Returns
  -------
  object
      self (TODO: WHY? Who calls this function?)
