 For harmonic functions, we get the following classification of removable
 singularities, which is sharp, that is, best possible.
 The harmonic function $\log \sabs{z}$
-has a nonremovable singularity at the origin, and any function

 that blows up any slower than that, doesn't actually blow up and, in fact,
 extends to be
 harmonic at the origin.
