hey, it's not like i started to divert it ;-), it's just that you said that "The last really big "trivial" issue with bypassing noexec on mounted filesystems was closed" whereas it's simply not true, better not spread this.
The ld-linux.so bypass *was* really big and trivial. Although it's still possible to do the whole mmap()/mprotect() thing to *still* get an executable, I'd classify it as "some thought and skill required" as opposed to "type this command line". It's not almost-impossible, but I'd rate it a notch above "trivial"....
