 Hmmm....
 Maybe the kernel should be keeping a vnode reference of the directory
 a program was loaded on.
 Then something like open("//$ORIGIN/<path>"...) could be used.
 Or maybe openat() could have some magic fd numbers.
 
 Of course, you need to DTRT when a program chroots.
 If $ORIGIN is inside the chroot, $ORIGIN relative paths should still work
 (and if outside, must not).
