POE is a framework for cooperative, event driven multitasking in Perl. Other languages have similar frameworks. Python has Twisted. TCL has "the event loop". POE originally was developed as the core of a persistent object server and runtime environment. It has evolved into a general purpose multitasking and networking framework, encompassing and providing a consistent interface to other event loops such as Event and the Tk and Gtk toolkits.
