Well, that is what I thought the goal was, but looking at the sigframe
code again it doesn't work that way.  If it did work that way then the
current call to call_signal_handler_now in sigreturn wouldn't be
necessary, although the stack pressue would be even greater.

So, I don't know why I put that explicit call in that function.  It's
probably superfluous, as you suspect.
