        many users and especially to Eros Albertazzi 
        <eros@lamel.bo.cnr.it> for reporting this.
 
+7.     Found a workaroung for the dump deadlock problem (3 childs 
+       stuck in pause(), father in read()). The workaround seems
+       to work for me and several beta-testers. If it doesn't work
+       for you, please report back.
