   Thanks for the reminder. I have added a new ./configure option --with-viewfromoptions=0 which will remove all of that overhead and likely perform better than the "hack" I suggested to apply earlier. This is in the branch barry/fixes-for-release-1 and will be in master if it passes all the test.

   I'll also remind you of the option --with-errorchecking=0 which turns off additional overhead that in theory is not needed in production runs and could help a bit more when using many small solvers.

  Please let us know if there are any difficulties.
