Your message begs some additional questions and a comment. 1) Which message from John Dyson are you referring to? I don't recall a technically detailed message from him on this subject for 2+ months. 2) Where are John Dyson's patches currently available? 3) I thought that John Dyson's patches had been committed long ago. Were they not committed because of stability problems, performance problems, lack of a warm body to do it, etc.? You request that I "write regression testing code to prove that it works". Regression testing does nothing more than prevent old bugs from reappearing. It proves nothing other than that old bugs haven't reappeared, and that assumes that the regression tests are written correctly to test for the bugs rather than their symptoms. Don't get me wrong; I'm a proponent of regression testing, but it won't achieve what you're asking for. Are you just asking for stability testing of the patches, or something else in addition?
