#1382: scipy.sparse.linalg.gmres is not reentrant

     Type:  defect            |      Status:  new     
 Priority:  normal            |   Milestone:  0.9.0

 SciPy's GMRES routine is backed by a Fortran routine that uses SAVE
 statements. This means that one cannot use GMRES for sub-solves within
 GMRES's invocation of a linear operator. While this may be a bad idea
 anyway, there's no real reason not to support this.
