Ummm, I can't reproduce the case of huge memory increase by
make-frame.  Can't you find a testcase to reproduce it
without your mpc.el?

By the way, I can observe about 1M memory increase, but at
the moment, I don't know where that memory is used.  At
least, font-objects and font-entities are shared by frames.
