I'd be somewhat surprised if there's a platform out there on which we  
run where strlen(NULL) *doesn't* crash; on most if not all platforms  
on which we run:

	1) NULL has all of its bits zero;

	2) at least one page of address space starting at 0 is deliberately  
missing (to catch null-pointer dereferences);

and I suspect most if not all implementations of strlen() don't  
explicitly check for a null argument.
