It doesn't really, not on Windows which has no AIO for example.  That's
why I suggested:

- assessing what code is GPL and what are the dependencies on it

- only including the formats in the library + a synchronous file
protocol.  No NBD, no libiscsi, no hdev, etc.

My suspicion is that with this strategy the only complicated dependency
is on coroutines.
