Those patches (I tested them together) do indeed appear to work around
the freezes I was encountering with io-thread enabled on OS X.
I get dma timeout errors when trying to boot Linux, but they don't
seem related to this patch as I got the same errors with the patches I
submitted a couple of weeks ago.
