Speaking of more Boost centric stuff? There has been any proposal of a coroutine library? I think it should definitely be useful and not really that hard to implement (fibers on windows and makecontext or the setjump/sigaltstack trick on unices). Anyone interested?
IIRC there was an article in C++ user's journal which implemented coroutines using fibres on windows and threads on unix. I'll have a look for it later. Also there are these article on fibres (these are the 2nd and 3rd parts, the first doesn't seem to be available): http://blogs.msdn.com/oldnewthing/archive/2004/12/30/344281.aspx http://blogs.msdn.com/oldnewthing/archive/2004/12/31/344799.aspx Make sure you read the third part - it demonstrates that fibre-safety is very different to thread safety (similar warning apply to coroutines in general). I think setjump would also have some serious problems - you could only have a single coroutine at a time and it could lead to undefined behaviour in lots of nasty ways. Daniel
