Your explaination is correct - it's difficult to protect the syscall table and so this happened. Personally I think it would be nice to be able to modify it more easily but that would require some redesign to add the various protections necessary. For example when the next exploit comes out which affects the vm syscalls I'd prefer a loadable module fix. (this is speaking as an occasional admin with production boxes kicking around that we rely upon not needed to be rebooted every 5 minutes - i.e. most so called "real world" users).
