Taxonomy synchronization caching bug

The i18nsync module synchronizes taxonomies before synchronizing fields, but during the field synchronization, it loads the node and does a node_save(). The node_load() is loaded a cached version of the node, and thus, when the node_save() is over-writing the taxonomy terms that were synchronized in the taxonomy synchronization.

You would hope that the solution would be as simple as passing the $reset flag to the node_load() of the translation nodes. However, because taxonomy caches it's values in static variables that aren't reset by node_load's reset, you have to actually manually get the current taxonomy values.

This problem appears solved in Drupal 7.x with drupal_static_reset(), but lingers in along in 5.x and 6.x.
