Using variable_set() is a very expensive operation that can cause cache stampedes and other horrible side effects for performance. This module simply adds a timestamp column to the variables table to track down which variables are changing.
When conditional CSS and JS is added to a page, this can cause a frequent number of cache rebuilds based on calls to drupal_build_css_cache and drupal_build_js_cache. This module forces conditional files to not be aggregated.
Small utility module that allows Drupal 7 admins to add and edit core taxonomy term synonyms. This module is purely for life support, not additional functionality. It requires a taxonomy_term_synonym table leftover from a Drupal 6 core Drupal installation. So, it's really only useful in the case that a Drupal site has been upgraded from 6 to 7, and you don't feel like/can't move your core term synonyms to a new system (entity fields).
