to avoid the need to block the changed handler, you may actually want  
to use the "insert-text" signal.  whereas "changed" is emitted after  
the change has happened, "insert-text" is emitted before the change, to  
give you the opportunity to mangle or otherwise validate the text  
before insertion.

see Gtk2/examples/insert_text_test.pl , which uses this signal to  
prevent the user from inserting
"#", turn "-" into "_", and turn "ee" into "whee".
