--- Comment #3 from Paul Gofman <pgofman at codeweavers.com> ---
I’d expect solution 1 to have a very unfortunate network performance impact,
this will make even fully synchronous socket io always take a server async and
possibly SIGUSR roundtrip. Note also that the sockets created with socket() are
capable of async io by default, so checking for socket flags won’t change much
in the majority of cases. This probably needs something neater. I don’t know,
maybe some sort of io request versioning can work?
