I'm not opposed, though the situation is confusing enough I'd like to have somebody confirm that my previous analysis makes sense (otherwise, this is just adding cruft to the Makefile :) ).

Sadly, I can't seem to replicate the original problem, even doing something like:

  n=1
  while true; do
    make clean;
    if ! make -j4; then break; fi
    echo $n; n=$(($n+1))
  done

(and I tried several variations). It ran for 20 minutes without failing. My suspicion is that there may be some particular state that triggers the race condition, but I can't seem to figure it out.
