* <p>
* This is not an atomic operation; A child may be deleted
* during the iteration through the child entries. If this happens,

* entry ommitted.

* @param path path
* @return a possibly empty map of child entries listed by
* their short name.
* @throws PathNotFoundException path is not in the registry.
* @throws InvalidPathnameException the path is invalid.
