Problems with `--nonoptimized` flag

The n/--nonoptimited flag doesn't work as expected:

• Running mono scallion/bin/Debug/scallion.exe test instantly outputs a key, running the same command with the -n / --nonoptimized flag however never outputs any keys.
• mono scallion/bin/Debug/scallion.exe -d1 test runs with Speed:3617,0MH/s, the same command with -n only runs at Speed:154,6MH/s

BTW: I use this flag as I run into the same problem as described in #62

for me its exactly the other way around - running with -n the speed is increased by x30 or something. However it can also not find any results

-n sped it up tremendously(4.5k optimized to 11k non optimized) for me but couldnt find a key containing a single character.

It seems the nonoptimized mode hits some esoteric bug in the driver. Likely I did something unsafe/out of spec that just happened to work on my old Radeon card. I'll have to figure out a validation test to check that. Unfortunately, the only modern configuration I have to test GPU stuff is an nVidia 970.

Ugh alright, I can reproduce this on my 970 under Windows (which I use solely for gaming and which does not have a dev environment), but not under Linux on the same hardware. So resolving this will have to wait until I next have the time + motivation to set up Visual Studio or Monodevelop on Windows.
