Perhaps it would be easier for all callers if the (inner) handler that
allocates the hash table installs a cleanup handler on it that releases all
the svn_error_t instances on pool cleanup of the release pool?
Now all callers that have access to the results have to cover for the
hopefully unlikely case where there are both global and per node errors,
while such a cleanup handler would allow all of them to use the standard
(The code iterating the hash would also have to cover for errors further in
the hash table, etc.)
