It's wrong layering. It's something like if TCP buffers were kept on disk.
Writing data to disk normally happens in two layers:
- in the OS ("swap" per se)
- in the business logic (databases)
So, ZMQ_SWAP can be either considered to be a swapping feature that
kicks in in case of memory overload, in which case it should be (and it
is) implemented by the OS.
Or, it could be considered to a database, in which case it should be
moved to the application on top of 0MQ.
