/**
* List children of a directory and retrieve their
* {@link RegistryPathStatus} values.
* <p>
* This is not an atomic operation; A child may be deleted
* during the iteration through the child entries. If this happens,
* the <code>PathNotFoundException</code> is caught and that child
* 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.
* @throws IOException Any other IO Exception
