Using "programming by permutation" pattern I've finally solved that
thing: filter
for some reason doesn't close file after XMLFilterBase.parse(<file_name>);
even after del filter; Workaround for this is to pass <file_descriptor>
instead of <file_name> to XMLFilterBase.parse() and then explicitly close
file or put this call in with-block.
