I haven't implemented a thread scheduler in some years, but I am more familiar with what's required than many who state an opinion on M:N vs. 1:1. My instinct says that M:N is the superior solution - I don't have anything to prove this and certainly it'll be tricky, but generally anything which increases parallelisability will increase scalability. I had been watching your work from afar just out of interest in how you do with a real M:N implementation. Someone asked for my library to work on FreeBSD, so now I'm actually part of the process. I look forward to it.
