Changing the tid of submitting tasks makes it unsuitable for sys_io_*()
or posix aio users as it stands.  Maybe we could swap tids on the
switch, but we'd probably then have to audit the life time of tid ->
task_struct users in the kernel.

And there's still the question of what ptrace is supposed to do.
