I know, I know, the best way to handle them is not to let them get there in the first place, but let's say they *DID* get there.
I wrote up a description of how I've handled a whole section going slack on a 187-yard beam. I couldn't have some fiddly thing that needed my attention all the time. I needed something that I could monitor from the bench and that would let me go 10 yards at a stretch before I had to do anything with it.
You can see some pictures and read a description over on my blog:

How do y'all handle things like this when they come up?
