Optimization looks really efficient. Here is image after optimizations. I
can't find any difference. While previously it took ~30 hours, now it use no
more 2 hours on my poor PII 233 with a lot of tasks. Number of samples vary
from 1 to 10001. If somebody is interested then below is output stream:

  Remove bounds........On  Split unions........Off
