Thanks. The issues remaining seem to have just to do with the fact that
iterative inversion inside iterative eigenvalue problem solver is too
inaccurate in single precision (or, the tolerances used in the test are
not OK). I think we'll just disable these tests for rc2, like here:

    https://github.com/pv/scipy-work/tree/bug/arpack-tol-0101

The ARPACK routines themselves run all the time in double precision, and
the double precision test suite appears to pass without problems, so
everything should be OK.
