It is likely that, if you develop a medium to large sized application for  
a customer, memory leaks will appear at the customers site. It will often  
be very difficult to reproduce the situation and find the leak. If you  
want to produce quality software, it is best to be sure what you are doing  
during the whole development process. There should be a set of guidelines,  
on how to prevent space leaks.
