Follow-up Comment #2:

No differences.  But I removed the callso to gca() and gcf() in the
benchmarking just to make sure they were unreleated.


octave:1> hf = figure
hf =  1
octave:2> hax = gca
hax = -18.142
octave:3> tic; for i=1:10_000; ishold(); endfor; toc
Elapsed time is 1.63488 seconds.
octave:4> tic; for i=1:10_000; ishold(hf); endfor; toc
Elapsed time is 1.64144 seconds.
octave:5> tic; for i=1:10_000; ishold(hax); endfor; toc
Elapsed time is 5.15146 seconds.
