IMO, writting the fiber functions by itself doesn't seem too complicated (mainly coroutines, and a couples of setjmp/longjmp should do the trick) we may have a bit more trouble trying to set up the same layout for the TEB (NT_TIB) as requested (mostly because two APIs for fibers are actually macros directly accessing the TEB)
