I think this is pretty useless obfuscation.  We're not going to have
pluggable checkpoint/restart implementations, are we?  So, why bother
putting it in a module?

I can understand that it's easier to develop your code when it's in a
module and you don't have to reboot the machine to load a new kernel
each time.  But, that's an individual developer thing, and doesn't
belong in an upstream submission.

I know people have given you a hard time for this in the past.  Why is
it still here?
