If check-webkit-style told you to indent the initializer list flush to
the right, then it's got a bug. :)

Turns out I can't find this rule in style guide. I might have made it
up or imported from another style guide. In general, it's a better
idea to have short source files that accomplish a well-defined,
easy-to-verify task. One class per file helps here.

I'll look at that patch in more detail again.

I'm not sure if it's the in the style guide, but static initializers
won't even compile on some platforms (e.g., mac). They run at
unpredictable times and impact startup performance. Typically the way
we work around this is by having a function you call to get a pointer
to the object and keeping the static as a local in that function using
the DEFINE_STATIC_LOCAL macro. You can search the code base for
examples of this pattern.

WebKit has a high bar for code quality. Other ports (e.g., Chromium)
when through similar review processes when they landed too. There are
certainly other development models which favor
commit-first-then-revise. Historically, WebKit has taken the approach
of breaking large efforts like this up into small pieces and reviewing
Honestly, I was probably a bit aggressive in r-ing your patches.
Hopefully you won't take that personally. My hope was to get the ball
rolling again because the work on the WINCE port seemed to have
stalled out. Having a bunch of r? patches languishing in the review
queue isn't really helpful to anyone.
