Achieving thread safety within a plot steam is more challenging and would require a fair number of mutex controls.
Hi Jim, I am sure you are right, but could you expand on that statement so I would better understand the development challenges that we would face? For example, I am interested in the question of whether (1) it is a fundamental misdesign of PLplot that requires it to have all those mutex controls for thread safety so that the better choice would be to change the design or (2) are there so many positives concerning the present design compared to more naturally thread-safe alternatives that the only choice we should consider for thread safety is those mutex controls?
