no, i think that conclusion is wrong. The FC1 glibc and vdso problems *when mixing a FC2 kernel with a FC1 glibc* were due to exec-shield enforcing non-exec for the vdso.

this bug has nothing to do with nonexec restrictions. [ Also, this all was _years_ and hundreds of bugs ago, when upstream's position was still a cocky "who the hell needs protection against overflows" and "go away with this non-exec crap" so we were pretty much alone trying to introduce those features. So any suggestion of intention on our part would be quite unfair. ]
