That was deliberate. Especially virHashFree doesn't > clear the pointer, the code which we have does. Oh, and one more reason. Those hash tables are allocated directly by the glib function since they don't use strings as keys which is the only wrapper that virHash provides, thus they should not be freed by the wrappers.
