Then it makes sense to have these in Octave itself.. However looking at
the engOpen command from the above link it appears that in fact Matlab
uses something like a fork/exec to create an entirely new process with
the Matlab instance running in it, rather than use a thread in the
current process, thus avoiding all the issues of thread safety. So what
you are proposing in fact goes beyond what is implemented in the Matlab
engine..
