If he is just going to cherry pick patches, then that can be all
automated using git directly, using a commit hook to test the commit
(and reject it if it fails). Something that everybody should have if
running the test suite weren't so slow :P

What you can do is have a git repository in the test suite server, and
plug git to the autotester, and make it only succeed if the autotester
result was good, the resulting repository will NEVER have a non-working
DMD. This way the testing is asynchronous, so it doesn't bother the
developer, but you also make sure the "good" public repository is always
healthy, something that is not happening now because is the other way
around. Walter first pushes changes to the "good" public repository and
the autotester runs after the commits are published, so there is no way
to undo the commits and fix them privately.
