For queries stored in the database, locks on the XQuery document are now only held until the query is compiled. After compilation the locks are released which allows the XQuery to execute concurrently whilst a user can also edit and replace the XQuery document.
Additionally, a number of resource leaks inherited from eXist-db from XQueries executed by the XML:DB and XML-RPC APIs have now been resolved.
