@ghobson - "you did it" :-)

got 1 block throughout the night solo with new binary on ubuntu 16.04.
I did expect 2 blocks but right now hashrate increases so it might be ok.

How long this will show up "immature" in the wallet?
The block is there since 8 hours now - I know for the coinspool it
takes 360 rounds to be balanced.

For windows I'm out - but others verified it to be ok already.

I can also conform about 20% higher hashrate.

Great stuff - thx to you ghobson :-)
