Why bother transfering just text ?  That makes all the rich formats
mostly useless.

Try that operation with kspread or Gnumeric.  1meg is trivial to
generate when you're spewing xml.  Multiply that by a number of
supported formats and the amount of data gets large.

Toolkit support for notifying of impending exit so that the
clipboard could save all of the supported formats seems like a
stronger solution.  Gnumeric has recevied alot of bug
reports/complaints when Klipper is enabled.
