There might be more than one type of stream actually.
The FIFO_Streams, I guess, serve the purpose of providing an inter-task
pipe line. Which BTW should also provide blocking on being empty/full
rather than raising End_Error.
Other memory-mapped streams are streams on top of a contiguous regular
array. You write into it via stream interface and you get a slice of the
written data. And conversely you store a slice, and then you read it out
via the stream. This is a bit different from FIFO / ring buffer stream.
