What do people think about making Hirokazu Yamamoto a committer?  I rarely see any mailing list posts from him, but he sure makes up for it in terms of patches submitted to the issue tracker.  As far as I can tell (I've noticed his regular involvement via patches and whatnot for well over a year), he's a pretty switched on guy with a lot of Windows experience -- every time trunk fails to build with vc6/7/8, for example, he's got patches lined up.
