Actually this is an understatement. Every feature (and I do mean
_every_) that went from -rt into mainline, undertook 3 or more rewrites
before it was acceptable for mainline. And every time, the end result
made the -rt patch set better as a whole.

Not to mention, that a lot of the early stuff also cleaned up mainline.
You can't have Real-Time without having a clean kernel. And as you
stated, a lot of those patches to clean up the kernel, no one even knew
that the real reason was to help the -rt patch set. They were well
disguised Trojan horses.

Darn, it looks like you are onto our scheme.
