I won't call it a hack. Because memset obviously can't go on to call memset.

Realistically, the default case that uses D itself, won't need more than 
a single function to implement. For optimized versions you must use 
assembly. Where the problem won't manifest anyway.

However this would be a wonderful candidate for a pragma to disable the 
calling to memset and friends.
