Smarter time management near stop limit This patch makes Stockfish search same depth again if > 60% of optimum time is already used, instead of trying the next iteration. The idea is that the next iteration will generally take about the same amount of time as has already been used in total. When we are likely to begin the last iteration, as judged by total time taken so far > 0.6 * optimum time, searching the last depth again instead of increasing the depth still helps the other threads in lazy SMP and prepares better move ordering for the next moves.
