With this change, problems (e.g. pointer aliasing bugs) that occur
with non-DEBUG production kernels may mysteriously go away on
DEBUG kernels, making the problems harder to diagnose.  If we are
going to keep things like this, perhaps it would be a good idea to
carefully document this feature, along with the appropriate way to
work around it and go about debugging.  Thoughts?
