A thread is a flow of control through a program with a single execution point.Threads are one of the pieces of a process. Every process has at least one thread and, up until now, every process running Perl had only one thread. With 5.005, though, one can create extra threads. In one implementation model, a program is divided into several parts and each part is assigned to a thread. If you are using Pipeline model, then the dependent thread has to wait for the completion of the task by the thread on which it is dependent.
You can learn more about threads from http://www.mkssoftware.com/docs/man5/perlthrtut.5.asp Cheers !!
