>From `perldoc -f waitpid`: On some systems, a value of 0 indicates that there are processes still running. In other words, waitpid can return a value which is not the pid of the child you requested. Therefore redo, since it's a foreach loop. This, of course, is only true on some systems; it may not be true on yours. -- Just my 0.00000002 million dollars worth, Shawn Programming is as much about organization and communication as it is about coding.
