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?
