Gathering session statistics on a global temporary table (GTT) are immediately invalidating some dependent shared child cursors. This invalidation is unnecessary since these cursors will only be used by sessions using the (unchanged) shared stats.
This causes excess parsing, especially for cursors used to load the GTT prior to gathering session-specific stats.
