What !? I really don't get this, what are you waiting for? Why is
rescheduling making things better.

We need to wait for the last dyntick to fire before we can return to
userspace.  There are plenty of options as to what we can do in the
meanwhile.

Why not keep your _TIF_TASK_ISOLATION_FOO flag set and re-enter the
loop?

I really don't see how setting TIF_NEED_RESCHED is helping anything.
