Its not exactly convenient either, especially in the case of modular 
code that may be developed by different people. Anyways, like I said I 
have a solution in my framework to make life of module developers 
easier. Obviously proper nested transactions would be the ideal, but so 
it goes. I was just throwing this out here when I saw Peter's comment.
