Using HotShot to do Performance Timing in Chandler

The only tricky part about using hotshot is making the call that you want to do timing for. You pass in a callable, *args, and **kwds. In the example below I called super(DetailRoot, self).render without any args or kwds since no parameters are needed.

        import hotshot, hotshot.stats
        profiler = hotshot.Profile('DetailViewProfile.hotshot')
        args = []
        kwds = {}
        profiler.runcall(super(DetailRoot, self).render, *args, **kwds)
        profiler.close()
        stats = hotshot.stats.load('DetailViewProfile.hotshot')
        stats.strip_dirs()
        stats.sort_stats('time', 'calls')
        stats.print_stats(50)        
        stats.sort_stats('calls')
        stats.print_stats(10)        
        stats.sort_stats('cum')
        stats.print_stats(10)  

It uses stdout to output three fairly self-explanitory profiles.
