Hopefully until it's finished (finally). I realized the problem with it was that I didn't have enough stuff in the plot - I didn't know enough about why the stuff was happening, and I couldn't make everything come together in a way that made sense. I think I've got that all sorted out now (in my brain at least), and it's just a question of getting it down on paper.
It'll be good to finally see this particular project come together and finish. God knows I've spent enough time dithering around with it.
Anyway, onward.
