    As long as syslog uses a connected socket (which it does), and doesn't
    flag MSG_NOWAIT (which it doesn't), there isn't anything in the kernel
    source that looks like the code will fail under cpu/memory/whatever
    contention.
    
    Just because UDP datagrams are unreliable that doesn't mean that UNIX
    datagrams are too.
