My placeholder "collector"  is attached.  Note that you can't use
it with PCH; doing a PCH experiment might be interesting too,
but it would be harder.  I also made the obvious changes in the
configure script and makefile to accept --with-gc=placeholder.

As you can see, I'm doing things in the maximally simpleminded
way.
