Have you tested the change?
This is a good point.
If you can make this change and still boot your system with a rebuilt
kernel, then there is hope that your claims are true.
The basic argument would be:
* Change kernel header to make EWOULDBLOCK == AGAIN.
* Rebuild kernel.
* Boot system.
* Verify system is semifunctional, networking, IO, disk, XVnc, etc.
That would go a long way to showing that most of the system works.
Then if you emerge the world against those changed headers and it goes
well, then we might be talking about it being a low-impact change.
I've rebuilt the kernel with the change and I can't see any impact.
NFS/SSH works fine and upgrading a few packages doesn't show any issue.
I don't have X on that box.
