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"....
