[Interest] Faster QXmlStreamWriter?

[Vadim Peretokin]

Thanks! That helped remove the resize operation from the profiling data,
but QBuffer::writeData is still there, and the overall time didn't change
much.

Is there anything else I can look at, or is this a dead end then - requires
a different serialization solution altogether (a lot of work)?
