During install/upgrade, caching is disabled. This change provides a way to temporarily enable caching (using in-memory cache storage only) within a specific function; caches are deleted afterwards. Adding this to two locations improves install performance quite a lot. Caching is not enabled during the parts of plugin installation that can vary for individual plugins (install.php/upgrade.php) as these might be relying on its absence, for example by making direct database changes.
