Thank you for summarizing and requesting feedback. It's nice for those who
didn't attend your presentation to see the current results and be able to
provide feedback.

One issue that continually fails to gain sustainable traction is identifying
the root causes and fixing the 1.9.x IO performance regressions on Windows.

Until this issue is added to high profile lists like yours, prioritized, and
viewed as important to MRI's future by Matz and ruby-core, I'm concerned
whether it will ever get fixed. And yes, I'm aware of Luis' recent
activities in investigating refactoring opportunities in io.c, file.c, etc,
and others past efforts.

From my perspective, it's simple. Either it's important to MRI's future (and
by extension Ruby the language) to be a great multi-platform implementation,
or it is not. If best-of-breed multi-platform support [1] is important,
prioritize fixing the current MRI-on-Windows performance regressions in a
timely manner given the current resourcing realities.

I request that you add "Fix Windows 1.9.x performance regressions" to your
2.0 list.

[1] As an example, see the great multi-platform efforts being done in
https://github.com/joyent/libuv
    for node and other usages. See how easy it is to build and test the
library on Windows. See that
    node has a prebuilt exe available for Windows at http://nodejs.org/ at
v0.5.8 not 1.x or 2.x

is too late that the only things one never regrets are one's mistakes.
