never interrupt global benchmark with found nonces
...
fix some algo weird hashrates (like blake)
and reset device between algos, for better accuracy
but this reset doesnt seems enough to bench all algos correctly...
to test on linux, could be a driver issue...
heavy: fix first alloc and indent with tabs...

On windows the gpu memory can be allocated by other processes
+ some cleanup in algos... (free/gpulog)

intensity: do not reduce throughput before init
...
Else the memory allocated could be less than required later
btw, use the new "cuda" function to apply intensity/throughput

The core problem was the cuda hefty Thread per block set to high
but took me several hours to find that...
btw... +25% in heavy 12500 with 256 threads per block... vs 128 & 512
if max reg count is set to 80...
