Thanks.  A couple of comments:

 . You mention RUNTESTFLAGS that is not otherwise documented in
   README.  I understand that you mention it (and the solution via
   setting RUNTESTFLAGS) as ``gotcha'' for those who use this variable
   for reasons unrelated to -j.  If so, I would suggest to make it an
   explicit note, something like this (the parens are deliberate):

    (Note that setting `RUNTESTFLAGS' then, by default, the tests will
    be run serially even under -j.  You can override this and force a
    parallel run ...)

 . I think we should say that using -j significantly cuts the time for
   running the test suite.  Otherwise, the reader would not
   necessarily understand why she would like to use -j.
