Mats, I agree with you that this needs changing. Hoe does:

The common-practice requirement cannot resolve these issues. Pre-POSIX 
terminal/serial I/O had similar issues, the System-V implementation was 
quite different from the BSD one. It was resolved then by defining a new

It would be tragic if there would be multiple Linux implementations. I 
suggest that this issue should be put on the roadmap, and that we modify 
the definition to reflect whatever crystalizes out in the future.

If we can avoid it we should not try to reinvent the wheel. Someone 
involved in the TrustedBSD project is trying to gain access to specs for
