1) Only use || around variables. Not class names. (|IOThread::Globals| and
|IOThread| are both incorrect)
2) Be careful about describing too much of the implementation. Does this enable
the DataReductionProxy? Configure it to be enabled? What shared state? Etc.

Done.

1) Reformat this. Your style is non-compliant. "git cl format' can help
2) Don't use || around UIThread

Use "the UI thread" and "the IO thread" to refer to these concepts.
