Separate file executions per subject makes more sense in a number of 
ways actually, since one tool could have side-effects that may affect 
the other, and their order of execution may affect relevant results, 
such as if caching is used.

If we want an easy way to put things side by side like combined 
executions could give you, then something analagous to a separate 
test harness script could be used for that.
