Wish does not release the system resources it uses even when it exits normally. Run through the widget demo, exit and look at the
system resources count. You may find it dropped by 17%. During the widget demo, monitoring system resources found that wish
does not seem to release system resources when it destroys widgets. During a wish session free resources just keep declining.
Given this situation, large wish applications may slow down or crash.
