Interesting, but it doesn't really help him debug it ;)

Unless there is some other way around it you can stop the kernel making it a 
system process by editing /usr/src/sys/kern/init_main.c around line 730 (in 
create_init).

Although some signal code seems to specialcase PID 1 so maybe that won't work 
either..
