What about klao's suggestion in ticket #19 about the possibility of seeding based on pid and/or timeofday etc? It might be a good idea, and it might require <ctime>. What is your opinion?

The randomize feature is a good idea and I would welcome it in the LEMON. However the solution is not obvious. In the c++ standard I have found just two functions which could be the source of the randomness(the clock() and the time() functions), but both of them have strict limitations. The good randomize function should work whenever we use more threads with own generators approximately started in the same time. Therefore, I suggest that it should be implemented different way for each compiler(for example MSVC does not supports getpid() function just _getpid()).
