Thank you, Michael!

>>.. like move objects that the script wants to access over into the worker process so that the script can have local access to them..
Very good idea! It will really help.
I checked the performance and found that the bottleneck in my script are getStartPt and getEndPt functions (only 900 segments per second, while script can process about 1500 segments per second).
The overall performance is ~600 instances per second.
Tomorrow I will move some functions to htm file.
