def put_object(offset, obj)
  # FIXME: This is a workaround to an issue I'm seeing in
  # 1.8.7-p352 (not tested in other 1.8's).  If I used the code
  # below that works in 1.9, then inside SharedMemoryIO#write, the
  # passed string object is 'terminated' (garbage collected?) and
  # won't respond to any methods...  This way is less efficient
  # since it involves the creation of an intermediate string, but
  # it works in 1.8.7-p352.

  io = SharedMemoryIO.new(self)
  io.seek(offset)
