In the end, it does help fixing /dev/io usage from multithreaded processes. - On i386 and amd64 the old behaviour is kept but multithreaded processes must use the new interface in order to work well. - Support for the other architectures is greatly improved, where necessary, by the necessity to define very small things now. Manpage update will happen shortly. Sponsored by: Sandvine Incorporated PR: threads/116181 Reviewed by: emaste, marcel MFC after: 3 weeks
