I think this is caused when multiple instances of Octave are generating
the plot figures concurrently, with make -jN. I can get these warnings
to go away with make -j1.

I can make this message appear sometimes by just running a few of the
plot scripts in parallel from the shell, for example

  $ ./run-octave --path ../doc/interpreter \
                 --eval 'sparseimages(pwd, "spchol", "pdf")' & \
    ./run-octave --path ../doc/interpreter \
                 --eval 'sparseimages(pwd, "spcholperm", "pdf")' & \
    ./run-octave --path ../doc/interpreter \
                 --eval 'sparseimages(pwd, "spmatrix", "pdf")' &

Running that a few times is enough to trigger the message for me.
