    This suggests that a Streams module may be written in
    a special way to run in a multi-processor environment, whereas
    perhaps it is the implementation of the Streams facility that would
    most require careful design for multi-processor operation. The
    modules themselves should be oblivious to the nature of the cpu/s,
    especially if the advantages of standardization are to be maintained
    (given that the existing Streams specification from AT&T do not
    allow for multi-processor operation).

    It would be interesting to know of approaches taken to implement
    Streams for multi-processor operation.
