mpi.recv or mpi.irecv needs a buffer to store an incoming messenger and 
must know in advance the size of the buffer. For mpi.irecv.Robj to work, 
one needs to probe the incoming messenger size which is a block call. So 
there is no point to implment mpi.irecv.Robj unless there is an another 
nonblocking call to find the buffer size.
