Given that (a) no one objected and (b) it solves the problem, I've implemented
this suggestion in pefarrell/feature-submatrixfree-fallback of
https://bitbucket.org/pefarrell/petsc.

I didn't make a pull request because for some reason the pull request shows
tonnes of changes I had nothing to do with (I branched off Jason's branch,
made the fix and pushed, but bitbucket seems to be confused). Jason, could you
please review/cherry-pick 13006bad66cf92787ea508665d0b39f5c9b8d46f ?

I'd really appreciate getting all of this stuff into next as soon as possible.
It's been floating around in branches for months and I fear bitrot is setting
in. My code has depended on this for months and it all works fine.

Thanks,

Patrick
