[petsc-dev] Options setup logic is broken

[Matthew Knepley]

I have a PetscOptionsBegin/End() block. Inside, we create some contexts,
which
have PetscOptionsHead/Tail() blocks. This used to work fine, but I started
getting
a bizarre error.

It turned out that the part of the function after OptionsTail() had not
run. This was
because the PetscOptionsPublishCount was > 1. This happened because I had
moved the creation of a PetscObject inside the Begin/End block. This was the
first object created, so a ThreadComm communicator was created. This called
PetscThreadCommSetNThreads(), which called its own OptionsBegin/End block
which screwed up mine.

This is crazy.
