This is fine, but there are quite a few more references to "swapper" in the src tree. mac_cred_create_swapper() in particular is a misnomer now. I should have cleaned those up when I removed stack swapping.

sys/kern/init_main.c
534	I only used the same name as that is what threads get by default (and tools like ps, etc. treat identical names as a special case). I think if we want to give it a distinct name, we should maybe use something like "boot" or "startup" that reflects its role.
