Is there a reason why this and m_writeSmartPaste aren't set in the member
intializer list? It doesn't seem as though this is called from the constructor
either.

[hj.r.chung, 2014/07/18 04:00:27]

I'll upload another patch with both members in the initializer list.
And I think m_sequenceNumber shouldn't be set back to 0 in clear() since then it
will always be 1 after a write and won't be able to differentiate 2 consecutive
writes from no writes. The current code works for the test I wrote but will not
if we need more complex ones. I'll fix this.
