Just to say it a last time, THE CODE I'VE POSTED WAS NEVER MEANT FOR 
MERGING in that state. Regardless how many people will still come by and 
repeat that it was ugly, bad and broken to just use that as an 
additional argument against me.

I've absolutely no idea how you all start to test an idea and 
demonstrate it others, but I don't waste time on such tasks with looking 
for style, (premature) optimization or even races.

I know how write production ready code, doing such since a long time and 
I know how much time that costs, and I know that only fools (or students 
which have to show that they can write good code) spend this time for 
code which might end up in the waste bin anyway.
