I see a way to get rid of 1 sendto and put it in the error path. This way people
without audit support (which would be rare for this distro) would get the extra
sendto. This would solve the common use problem. You really need audit compiled
in for SE Linux avc messages to be full and complete.

I also see a few *minor* issues in the kernel that might save a couple clock
cycles, but no magic bullet.
