Limit number of threads for valgrind testing
Limit number of threads for valgrind testing

Limit the number of threads (--numThreadsPerLocale) for valgrind
testing.  This seems to help with the current remaining valgrind "the
'impossible' has happened" errors.  Specifically, all the 'impossible'
errors from last weekend's testing were due to "VG_N_THREADS is too
low".  Since we don't want to rebuild valgrind for every system we
have, I have limited the number of threads as we do for qthreads
testing.  In hand testing, this go rid of all the 'impossible' errors.
Hopefully it will work in the nightly.
