Last minute request!

Any chance of limiting the number of undo’s, since kalle suggected that it might be the reason for a “memory leak” I’ve noticed that all the patches I do with create node switching patches, get very large memory usage, very quickly. I think that this is the undo, after a while things start to go slow…
I like the undo most of the time, but a way of disabling or reducing it when needed would be most welcome!
