* A flag `--keep-going / -k' to keep building goals if one fails, as
much as possible. (This is similar to GNU Make's `-k' flag.) * Refactoring to implement this: previously we just bombed out when a build failed, but now we have to clean up. In particular this means that goals must be freed quickly --- they shouldn't hang around until the worker exits. So the worker now maintains weak pointers in order not to prevent garbage collection. * Documented the `-k' and `-j' flags.
