For now all ports implement swapcontext() by doing a system call. My
patch fixes a bug while keeping the system call based implementation.
Further work could make swapcontext() purely userland on ports where it
is possible. I think the patch I propose do not prevent doing so. It
even makes it easier since it introduces a libc stub for setcontext(),
which can be overriden.
If we cannot settle on that, we need to core to make a decision.
