Problem with new BE release candidate

Windows cmake builder is running new BE since yesterday. First thing that i noticed, is
the increase of buildtime. Previous version was consistent around 5 minutes, the new
candidate - more than 7. I doublechecked it by swapping BE's back and forth.

This might look not serious, but if this problem scales up, we are talking about 35
minutes of buildtime for someone who needed 25 minutes previously.
