John, please review

Randy, fyi

I'll drop the render_view_host.cc change from the CL, it's just here that it
compiles until http://codereview.chromium.org/8135028/ has landed

I'll also include a valgrind suppression for the intentional leak

John, I've wrapped the savable schemes in a singleton, so I can free the memory
on shutdown.

PTAL

ok

but why do you care about saving memory at shutdown? we want shutdown to be
faster, and that means not running destructors except where we must

I thought it was nicer to free all memory. However, I agree with you that it's
not really necessary. So I'll revert to my last version and commit
