Comment (by rhaas):

 Probably for the same reason the parameter file also hangs in OutputGH if
 carpetlib::barrier_between_stages = "yes" is set. The Processes hang in
 comstate.cc in the barrier 404924393 in comm_state::step and the
 MPI)Waitall in state_empty_recv_buffers (no line numbers since I put so
 many printf statements in that I am sure to misscount).
