long ago) supposed to be used as a cache for accessing the PML procs. But in all of the PMLs the PML proc contain only one field i.e. a pointer to the ompi_proc. This pointer can be accessed using the c_remote_group easily. Therefore, there is no meaning of keeping the PML procs around. Slim fast commit ... This commit was SVN r11730.
