set after we call mca_pml.pml_comm_add(). This allows us, in the destructor, to only call mca_pml.pml_comm_del() if the corresponding pml_comm_add() was called. In this way, if an error occurs during the construction of a communicator (e.g., attributes failing to copy, as in the Intel test MPI_Keyval3_c), we simply propagate the error up the stack so that an MPI exception can be generated -- not cause a failed assert() in teg's pml_del_comm(). This commit was SVN r5032.
