security setting in a distro), or turn it off and *know* this will break
certain older binaries?
Remember that if you're a distro with a million users, even if only 0.1% of
them still have old binaries, you just borked 1,000 user's machines. Now
compare that number to the number that will get hacked if you leave COMPAT_VDSO
on (remember that the *only* thing it stops is exploits that hard-code certain
