I have Dr. Cleaner (free version) running. It constantly displays my memory usage and once that starts to run up to 60-70% I know it is time to save/quit and restart what I was doing.

If I need shapes like this, I create a rough outline with the pen tool and then smooth that selection to get the curves right. Here's a quick and dirty example: I used the polygon option to create a rough shape, made a selection out of it and then simply used the smooth selection option.For this sort of shapes I find this quickest. You could also use the pen tool and create the whole shape manually but that's too work-intense for me personally.
