Patch is ok with a single change: Please add a "FIXME?" comment to:
else
RtlCaptureContext();
On second thought, calling RtlCaptureContext here is probably wrong.
What we really need is the context of the thread when calling
call_signal_handler I think. It would be better to call RtlCaptureContext
before calling call_signal_handler. But this requires a change in how
call_signal_handler is called.
We should discuss this at one point, I think.
Thanks,
