It seems like there's some sort of resource leak that can eventually lead to a
crash when the various components are opened and closed via lua scripting enough
times. I don't know exactly what is causing the problem, but I'll try and
figure it out. Some of the modifications to the lua-relation sections of the
program that Robin Cornelius has told me that he is experimenting with might
help this problem, e.g. linking into a lua dll.
