NAME
    POE::Exceptions - POE class for handling exceptions

SYNOPSIS
        use POE::Exceptions;

        POE::Session::Exception->create(
            inline_states => {
                _start => sub { print 'START';
                                $_[KERNEL]->sig('DIE','death_handled');
                                return 1; 
                              },
                death_handled => sub { print 'EXCEPTION CAUGHT' },
                _stop => { print 'END' }

        );

        $poe_kernel->run();

DISCUSSION
    POE::Exceptions extends POE to catch exceptions neatly. A new signal,
    "DIE", is introduced. This signal will be fired every time an exception
    occurs. (For those of you new to the term exception, an exception is
    whenever the code decides to bail out by "die"'ing.) If the signal
    handler returns 1 (as in the example above), POE will assume that the
    handler dealt with the signal appropriately. If the signal handler
    returns 0, POE will assume that the handler does not want to deal with
    the signal and POE will propgate the exception as if the handler never
    existed.

    Caveat: POE::Exceptions will die on its own in the case of a double
    exception fault. If the "DIE" signal handler itself throws an exception,
    POE::Exceptions will shut the program down and bail out.
