Ahhh.  Just like it can't print strings for "buf"?

	write(int fd, char *buf, size_t len)

Man, strace is stupid! ;)

If that's *really* a concern, why don't we just pass, say 4 or 5 longs

	sys_clonebig(unsigned long flags0, unsigned long flags1,
		     unsigned long flags2, unsigned long flags3);
