Review comment:
As I'm working on my new patch (to switch from ucontext API to
sigsetjmp/siglongjmp pair) I need to keep the sigjmp_buf inside the xcpcontext.
The problem is that you can't simply use a pointer and use dynamic memory
allocation because the heap memory is not initialized when up_initial_state()
is called for the Idle Task. We can have an array that can hold the sigjmp_buf
data but the size of this is arch dependent. Do you have a better solution to
this ?
