I've tried it both ways, and both ways my process is being killed, presumably by the O/S.
I will say it's an extra motivating factor to have few failing tests -- if more than two of my tests fail, all I see are
'.'s, 'E's, and 'F's, with no clues as to which test failed nor why. Thank goodness for '-v' and being able to specify
which method of which class to run!
