When we have several pending signals, have entered with the kernel
with large exception frame *and* have already built at least one

If that happens, subsequent sigframes are going to be garbage.
Not hard to fix - just need to find the "adjusted" frame first
and look for format/vector/sr/pc in it.

Please move this to "[MSch: ...] below...
