So I pulled this, but I'm not particularly happy with how this (very unusual) lock pollutes that pretty much every single file ends up including. So I'd really prefer to see the ww_mutex() support split up into , rather than making the compiler have to parse and remember that stuff when 99.99% of all files do not care about it or need it. Hmm?
