Ciao Samuele,

I see this has been asked before already on this list.
Sorry for not checking earlier! But I also see that it
is not impossible to implement chdir and friends in 
Java despite its security concerns as the following 
should make clear:

  http://www.hio.hen.nl/java/nl/nl/hen/ict/unix/Unix.html

Needless to say, I'd opt for Jython being more similar
to Python instead of Java, if for no other reason than 
the higher similarity of the "Jython" string to "Python"
than to "Java"! ;-)

Seriously, if it's possible to use chdir-like stuff why
not add it and make both happy, Java people missing it
*and* Python folks reusing their scripts...? Maybe some
Java guys will be more inclined to being dragged over
to Python?
