Rendering with all threads

First of all, I know that is experimental function but for 8 threads in my PC it's a pity.
When I use 1 thread, Kdenlive works fine but sometimes I have CPU bottleneck. It's not so bad but maybe, if I could use for preview 2=>8 threads at the same time, 1 thread was wouldn't so busy. It's not important but it's a pity.
Rendering works fine with all 8 threads and rendering time is more than twice faster vs with 1 thread.

Thanks for your report, this option has been removed altogether from Kdenlive since it is very buggy. We expect better support for multithreading in future versions of MLT.
