Support for memory allocation from multiple NUMA nodes
Support for memory allocation from multiple NUMA nodes

Added support for multichase to allocate memory from multiple NUMA
nodes. The -W flag is used to set the weights for the nodes that
memory will be allocated from. For example, -W 0:100,1:200,2:100
will allocate 25% of memory from node 0, 50% from node 1, and 25%
from node 2.
