But what about having texexec/perl calculate the checksums, writing them to 
an auxiliary file, and tex just reading them? And in any case, one can be 
sure that the mp code will not change during the same call to texexec (or 
can there be exceptions?), so that if, say, three tex runs are necessary, 
one run of mp would be sufficient. Setting some switch may be sufficient to 
achieve this.
