Wrapper to mpi4py's MPI.Intracomm class to avoid busy-waiting. As suggested by Lisandro Dalcin at: * http://code.google.com/p/mpi4py/issues/detail?id=4 and * https://groups.google.com/forum/?fromgroups=#!topic/mpi4py/nArVuMXyyZI

Scatter data across the nodes The default version apparently pickles the entire 'dataList', which can cause errors if the pickle size grows over 2^31 bytes due to fundamental problems with pickle in python 2. Instead, we send the data to each slave node in turn; this reduces the pickle size. @param dataList List of data to distribute; one per node (including root) @param root Index of root node @param tag Message tag (integer) @return Data for this node
