Comment 3 for bug 847227

Well, is very very tricky in the backend to do this, since syncdaemon will not allow you to enable/disable a single limit (either up or down), but only the 2 simultaneously (either both are off or both are on).

So, as a workaround for the original design, when the user decides to throttle a single limit, we enable throttling for all limits but set the not-throttled limit to a very high value.
