Modified parallel testing system so that parallel tests
launched on the local node do not use ssh to launch the
job.  This makes it possible to test using multiple cores
of a machine without doing any ssh-agent/-add commands,
for example.  I've tested this on a few machines and it
seems to be working correctly.  If anyone runs into
problems with it, please let me know.
