The only problem with adding new system calls is that we are stuck with
the interface until the end of time, so we must be sure not to get it
wrong. The same thing is true for any other interface such as ioctl
or extensions to existing system calls. People usually get away with
adding new ioctls more easily because it is less obvious when they
are added.
