[petsc-dev] [petsc4py] Issues with DMStag testing

[Lisandro Dalcin]

1) The tests were talking too long, so I had to reduce the number of tests.
https://bitbucket.org/petsc/petsc4py/commits/b73507143ba1f1615f76973f59ad9fb49c066d4c
Even after that change, TestDMStagCreate runs 1716 tests!! The tests
involving periodicity have been broken for a very long time without any
resolution, so I just disabled them.

2) There are memory leaks:
