LD_PRELOAD can't replace code inside a program, it can only replace one
shared library with another.
GSAppKitUserBundles is more powerful than LD_*, because it lets you modify
the app itself, not just the libraries it is linked with.
It's well-known that if you use shared libraries, you can't trust their
code. It is also well-known that if you use bundles, you can't even trust
YOUR code.
