Wrap-up of triage duty

All in all, it was a good week with lots of regressions getting
cleaned up -- thanks to everyone for their efforts.  The things
that snuck in at the last minute are:

- test_dot_locale_error starting to fail again, with the fix to
  the distributions/robust/arithmetic/performance failures

- SSCA2 comm counts improved, causing it to fail

+ memmaxExceedsLineno2 was resolved


Other changes are minor:

* updated paths to timing out nbody variations

* noted the reason that thread-ring tests are failing under GASNet is
  due to Sung limiting the number of threads for a valgrind run.
  Should probably be skipped or reduced to a smaller problem size for
  the correctness run.
