nit: this section should be moved downwards (after PPB_Testing).

Is it necessary that these messages are sync messages?
I have a quick look at the CL "Never submit: tentative Pepper IME" and haven't
found the reason why they need to be sync (at least the first two). Would you
please explain why?

[kinaba, 2011/09/27 02:49:27]

Done.
Oh, yes, there's no reason for them to be sync.
Changed to async. Thanks.
