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.
