[petsc-users] unsorted local columns in 3.8?

[Mark Adams]

This printed a little funny in gmail, snes/ex56 is running clean in the
first few loops (appended), but the last one is the one with a reduced
processor set. Still waiting. This is with 32 bit integers. I'm running
another with 64 bit integers.
