You are referring to the way it sometimes continues the status display
half way on a line, screwing everything up? (I think there is also a
problem relating to $d in the format string, but I'm not immediately
sure what to do about that).

Looking at the ktrace output, you'll see occasional "short writes" on
standard output. Write cannot flush the whole string, so the CR at the
end never gets printed. (Presumably Linux and FreeBSD have bigger I/O
buffers, or somehow manage to get tty writes out the door faster than
we can.)

The simplest solution is to put the CR at the beginning of the string:
