1) Work with petsc-dev http://www.mcs.anl.gov/petsc/developers/index.html
the threaded stuff is more mature.
2) You should not need petscthreadcomm.h in Fortran. Simply using OpenMP
progmas in your portion of the code.
3) See http://www.mcs.anl.gov/petsc/features/threads.html for a little bit
of detail and feel free to post additional questions on this mailing list.
