What does the Hand Pool do?

[extreme112]

I've read through the comments in the code and from what I understand it's responsible for limiting the number of hands on the screen. This can't be the only thing it does because I once forgot to add BrushHands to the pool, which caused some problems with interactions.

Glad to know all about this. So, Brush-hands is very important factor for preventing in some errors. Now I know the reason why I always face that problems and thanks for that.
