I have no idea about Perl - but there's probably some hideous black magic going on ;-) As for Java, making code thread safe *does* slow down the code. It is the very reason that the language designers made the collections API non-thread safe by default (you have to wrap the standard collections in a synchronised wrapper to make them thread safe). -- Ant... -- http://mail.python.org/mailman/listinfo/python-list
