Does this actually reflect reality?
task_set_name RPC has been added to GNU Mach. Before, the Mach debugger
arg on the stack using ugly heuristics (see
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
do_exec(). Also see the discussion on
translate fd or port to file name.
