If the command run by sudo is killed, the I/O log should still be
complete since the I/O log buffers are flushed on close.  The only
case where this would not be true is if the sudo process itself was
killed.  If you find that not to be the case then that is a bug in
sudo.  I'll update the documentation to make it clear that the
I/O logs will be complete if the command is killed by a signal.

There is another use case for not buffering, which is to make it
possible to watch the logs in real-time but no one has asked for
that yet :-)
