Buffers for inter-processor communications streams (UOPstream, UIPstream).
Use UOPstream to stream data into buffers, call finishedSends() to notify that data is in buffers and then use IUPstream to get data out of received buffers. Works with both blocking and nonBlocking. Does not make much sense with scheduled since there you would not need these explicit buffers.
Example usage:
