nit: wrong indent.

[ygorshenin1, 2013/02/05 12:45:31]

Done.

+  typedef ppapi::host::ReplyMessageContext ReplyMessageContext;

[yzshen1, 2013/01/24 18:45:03]

You could use a 'using' in the .cc file instead of typedef like this.

[ygorshenin1, 2013/02/05 12:45:31]

Done.

It would be good to comment on which thread each method runs on and which thread
each data member is accessed on.

[ygorshenin1, 2013/02/05 12:45:31]

Done.

Can you please rename OnResolve() and DoResolve()? They look too similar to
OnMsgResolve().
And please add comments about which thread they are run on, and what they do.

[ygorshenin1, 2013/02/05 12:45:31]

Done.

I don't see why we need these two private accessors. You could directly use the
data members, right?
