And I'm gald you do. You know that I admit if I screw
things up even in my change logs. Finally I'm sometimes just
the shield for screwups done by others. (No problem I can
take the heat :-).

Many people just do not realize that I don't hunt for the
easy fruits. I tend to solve fundamental things first before
getting down. (See for example the TCQ in and out
discussion I had with Jens - it turned out to be much
better to do the infrastructure thing at same time instead of
hacking up on the existing thing.)

Down to the point - there was *no way in hell* to
solve the PIO problems util:

1. The basic datastructures we have now where there.

2. The locking issues get resolved and take place on a sane
level.

3. The number of possible code flows got sanitized.

Heck, contrary to the habbits of many others I'm constantly
trying to explain even the reasoning behing the changes I do.
Not just what gets changes.

But fortunately right now we are indeed "getting just there" as
the fact shows that the last series of the IDE patches is moving
more and more down to the actual transport layer. And since
the overall structure starts to become more and more
clean even more and more people start to work together with
me on not just some very well separated areas like for
example host chip timing but the overall infrastructure as well.
(Adam, Bartek - I'm glad you are around :-).

Everybody out there proclaiming that this could have
all been solved far earlier by some kind of "easy" fix had just
enough of time to prove me worng on this issue.

Unless I get complains from people who work with me together
on the code itself I indeed tend to follow my own agenda
of prio.

It's that simple.
