   @xiaoxiang781216 We still need a way to create and switch to a new stack so ```ucontext``` functions can't be replaced with the sigsetjmp/siglongjmp. I looked at the Qemu implementation and it seems that they are using ucontext for task setup & creation and sigsetjmp/siglongjmp for everything else.
