Script that be configured to run with/without PySide and with/without
decorators

I use a decorator on all of my callbacks to record to a log file any exceptions
to help in debugging user issues.

When porting from PyQt to PySide, I found that if I am using a cross-thread
signal/slot and the slot decorator decorates a function that has my logging
decorator applied, it will not receive any of the signals.

Example:
    @Slot()
    @log_exception()
    def process(self):

Workarounds:
* Use PyQt
* Do not use decorator
* Move all slot logic to another function that is decorated, leaving the slot
to call it.  For example:
    @qt_compat.Slot(object)
    def _on_task_added(self, task):
        self.__on_task_added(task)

    @misc.log_exception(_moduleLogger)
    def __on_task_added(self, task):
This is a bit messy though and would be nice to have this fixed.

Attached code will autodetect the available bindings and try to run some
producer/consumer code.  When DECORATE is True and it is using PySide, the
script will never terminate on its own.  If DECORATE is False or PyQt is used,
it will print the results of the producer/consumer and exit.
