This series of patches implements coroutines method with sigaltstack. The flow of creation and management of the coroutines is quite similar to the coroutine-ucontext.c. The way to use sigaltstack to achieve the needed stack manipulation is done in a way quite similar to the GNU Portable Threads (file pth_mctx.c, variant 2).
This v2 has some corrections and improved patches, but it's essentially the same. At the moment, the default backend is ucontext (the former default method for coroutines).
