    Experimental PACK_TIGHT compile time option · c59e6d4a

    When set, the goal is to pack vnodes as tightly as possible - that is,
    to penalize wasted slots in assignments.
    One downside is that this will tend to make really lopsided mappings:
    eg. if you have 50 slots per pnode, and 51 vodes, you will end up
    mapping 50 to one and 1 to the other.
    The other downside is that I have not yet thought about how to balance
    this with link weights.
