changing threshold can cause the UI to freeze

For larger datasets, the length of time it takes to recompute the nway comparison can be non trivial. So if you increment through each threshold value it takes a long time to compute one, and then when it finishes starts to compute the next before the user can do anything.
Basically the nway recomputation needs to somehow be non-blocking.
