Just a side-note to say that I've got just this package running and
working with -fstack-protector.

I can also add that I've been doing x86 stable tracking with
-fstack-protector for almost a year now, sometimes things break, but
bugreports have been filed and things have been very smooth the last few
months.


+1  for recommending it to default.

Can somone take the time to benchmark this properly though?  we rather
shouldn't have many "oh this sucks 15% cpu"  rumours without substance. 
both string and integer, small and large software.

Some of the more interesting parts would be fex.  python performance and
performance of python apps.
