That's another thing that puzzles me...

At the time audio cards like the RMEs would be sitting on a PCI bus,
and the mmap area could/would be actual hardware buffers.
So then, mmapped mode would be the 'natural' way, with read()/write()
being implemented on top of it. But apparently it was the other way
