[Harry Potter] I think I read somewhere that the little thing that Harry saw in limbo (small part of voldy) was indeed how Voldemort had to exist forever after death as punishment for murder. How is suicide handled after death?

It wasn't a punishment imposed by external judgement, it was just how the nature of magic works in that universe.  He had torn his soul into so many pieces by murders, so that is just what his soul is now, and it is too damaged to enter afterlife.  And it is implied that the damage is caused by how you understand the nature of the act too, because Dumbledore said to Snape only Snape himself knows whether his euthanasia of Dumbledore will harm his soul.  

We don't know whether suicide tears your soul or not in that universe.  But it probably depends on whether you think that is an evil act or not.
