To run narcissus with jstests.py, change to the js/src/tests/ directory and run
the following command (which excludes tests that are particularly slow):
python jstests.py -d -j 4 $OBJDIR/njs -x slow-narcissus.txt
Currently, Narcissus is failing a number of tests. narcissus-failures.txt can
be used to ignore those tests. Note that narcissus-failures.txt also includes
all of the tests from slow-narcissus.txt.
python jstests.py -d -j 4 $OBJDIR/njs -x narcissus-failures.txt
