I haven't seen anything for this, this is not in the current Linus or mm 
releases.  Did I miss something?
   

Andi had some legitimate gripes over it - the patch was a bit messy and
could have some performance impact.  So I kinda forgot about it in the hope
that a nicer solution would come along.
 

Ok.  I searched and could not find Andi's email; do you have a pointer 
to it?  I'll fix the problems.

I looked at it, though, and the only possible performance hit I could 
find was that it copies the sa_handler data structure.  That's going to 
be hard to avoid.  And there was that big nasty line with too many "->" 
and "." setting sa_handler to SIG_DFL...

Thanks,
