 I think the committers need to prove as part of their patch that it doesn't break things.
 Maintainers can go back and say "Well, you haven't proved this or that" and can give suggestions
on how to prove it.

I like this. Responsibility of testing a patch lies with the patch 
submitter. If we make this the responsibility of the maintainer or 
committer we will foster a "throw it over the wall" mentality that will 
not be healthy in the long run. I do not think that this conflicts with 
Dave's definitions.

That said, we also have to be reasonable what constitutes testing. Not 
every contributor will be able to run a full test suite or test a given 
patch in all possible scenarios. Thus the responsibility of testing is 
really shared by many and not just the contributor - committer - 
maintainer chain. But the initial responsibility must lie with the 
contributor, IMHO.
