Thanks to Gunter Winkler and Karl Meerbergen for their help.

Using CXSparse the time spend in solving Ax=b went from 75% to 10% of
the total runtime, which was enough for now.  I estimate 50% of the
runtime is now in BLAS operations, so I might later try using an
optimized BLAS, and I'll try UMFpack then.
