Opinion:

It seems to me that the -l switch is used so infrequently that setting the
log to unbuffered or doing a fflush after each time your see that you have
written a line terminator to the terminal output wouldn't really have any
serious performance impact.  You might try it and see if there's any noticable
slow down.

BTW, you might want to think about what dlogin is doing for input and output.
It appears to at least look at stdin for input but opens /dev/tty for output.
This makes it inordinatly difficult to drive from a script or pipe the output
to something else as compared to copying the stdin/stdout descriptors...
