yep ... this was one of the original ideas: to extend the 'exception prone code section' with 'extra information'.
This 'extra information' is equivalent to a compile-time constant passed to a single instance of function.
Why i didnt implement it in csum_partial_copy_fromuser(): IMHO, we are trapped by our own concept: we are playing tricks with the compiler to implement a nonexistant compiler feature, and there seems to be no return :*( It's getting very ugly IMHO. I dont know where the right point is to wait for compiler support to emerge. If you think it's all cool enough, then fine with me ;)
