Both single and SMP sethostname/gethostname have a problem. If you get a page fault during the copy in a gethostname can return a corrupt nodename. If it has overwritten the previous 0 byte you can get a lot of crap in theory but I've never seen it do that
If you do two sethostnames and one of them sleeps you can get a mixed up or shortened hostname.
sethostname/sys_newuname/sys_gethostname/sys_setdomainname need a reader/writer lock on them.
