OTAs commonly end up in an inconsistent state if apps depend on changes to /sys. For example, the %sift changes break on OTA because %spider needs to be reloaded so that it's aware of the new thread type. This adds a %goad app, which reloads all apps after every change to /sys. Getting this to start OTA is nontrivial, but this pattern should work for apps in the future. The changes to clock shouldn't generally be necessary; they are only necessary here because we can't rely on hood to start goad, since hood fails to compile if it's run before zuse is reloaded. Once goad is active, this will cease to be a problem.
