I believe that it's possible. I think that Andrei does it (he posted commands 
related to that at one point, but I couldn't get them to work), but I don't 
know how. I just always run the whole test suite. This is a question that 
would probably be better asked on either the main list or the Phobos list, 
since the ones most likely to know are Phobos devs, and a number of them do 
not pay attention to D.Learn.
