With help from Brian, modify the ompi/proc/proc.c code to be more thread-safe. Remove the list operations from the ompi_proc_t constructor and destructor. Insert list appends to ompi_proc_init and ompi_proc_find_and_add as required, and protect those with thread locks. Let only the ompi_proc_finalize function actually remove objects from the ompi_proc_list.
Cleanup a few places where functions might return without unlocking a thread. Ensure the ompi_proc_world also does an OBJ_RETAIN so that the reference count on any subsequently released object is correct.
