[Interest] QueuedConnection, QByteArray, reserve, capacity

Actually I just checked 5.9 QByteArray sources and I must say that optimization on releasing memory than shrinking more then half is disabled for capacity reserved arrays. So, it’s already works as expected =)

That's exactly what I had understood and I said that we'd need to store the 
allocation policy somewhere in QByteArray's internals. And I'm rejecting that 
as too much overhead for the 99% case use of QByteArray.
