This is the expected behavior.  In the current implementation in trunk, re-
opening a file always returns the already-opened handler, so closing any of 
the handler, will automatically close all the others.  You can use the 
`File.isopen` attribute in order to determine if the status of the file 
handler and re-open it manually, if necessary.

This is not the same behaviour as `open()` in Python, but at least the above 
behaviour allows to re-open the same file many times.
