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()`.
