Hmm... indeed. We might revisit this at some point to make sure 
debugging in signal handlers works. For now, however, I will leave this 
out of the patch series. The Linux userspace platform has been broken 
for two months now, and that state is quite embarrassing, so I'd rather 
have this finally fixed.
Good point though and will be interesting to see what exactly they are 
pushing in there as CFI.
Thanks again,
Florian
