In my experience on x86 architecture using GCC, "memset(p, 0, len)" is  
substantially faster than a tight loop (between 2 & 10 times faster  
depending whether the loop is byte-by-byte or word-by-word). This is  
because GCC knows to optimize "memset" inline to a single instruction (or  
close to it).
