Limit glitch

I'm wondering whether this has been covered here before. I just noticed
that Limit often gives wrong results at jump discontinuities. For
example,  Limit[x/Abs[x], x->0]  returns 1. The pattern seems to be
that the right-sided limit is always given.

Does anyone know anything about this?
