As an aside, can count ever be larger than size_t?
Probably not in the communication or I/O functions since count refers to the number of items in the memory buffer, but it could be for the datatype constructor functions since datatypes can represent file layout.
How would you use a datatype that is larger than your address space? You can't read or write it, you can't send or receive it, you can't pack/unpack it... Am I missing something and a datatype like this would be useful? -Fab
