+A `task_set_name` RPC has been added to GNU Mach. Before, the Mach debugger
+looked for `arg[0]` on the stack using ugly heuristics (see
+`gnumach/i386/i386/db_interface.c`, `looks_like_command`...). Now we can let
+`exec` simply set the name and record it in `task_t`. After adding the RPC,
+glibc needs to be recompiled against the updated `mach.defs` to get access to
+it from userland, and exec would probably call it from `hurd/exec/exec.c`,
+`do_exec()`. Also see the discussion on
+[[open_issues/translate_fd_or_port_to_file_name]].
