Maps {@link ResultSet result-sets} to specific contextual datarelated to processing that {@link ResultSet result-sets}.
Implementation note: internally an {@link IdentityMap} is used to maintainthe mappings; {@link IdentityMap} was chosen because I'd rather not bedependent upon potentially bad {@link ResultSet#equals} and {ResultSet#hashCode}implementations.
Considering the JDBC-redesign work, would further like this contextual info not mapped seperately, but available based on the result set being processed. This would also allow maintaining a single mapping as we could reliably get notification of the result-set closing...
