this is implemented by extending the existing functionality for hints and leads to a significant reduction of the volume variables updates required. unfortunately, the performance with cached volume variables is basically identical to the non-cached case, so they are disabled by default... anyway, this makes the thermodynamic hints code more robust and cleaner, so it does not hurt to add it...
