No; only suid artswrapper has the necessary privs to change the kernel
scheduling priority of the artsd thread, and it (correctly, so I can't
assert that there's a security issue here ;) drops suid privs immediately
after this change. However, a more realistic workaround might be for
artswrapper to detect the kernel version and avoid fiddling with scheduler
policies at all on 2.4 (possibly in favor of setting nice levels instead, if
this is safe).
