The following question seems unusual, but if someone figures out how to do it then we can do a single mxEval() call for all the algebras in a model to test the algebras for conformability during mxRun before the optimizer is called, instead of one mxEval() call per algebra. This could speed up our test suite (not by much, expect something like 5 - 10% increase).
