I have implementation that moves arbitrary task :)

Is that the one that calls stop_machine() in order to move a task
around? That seemed a little heavyweight ...

Nope :) I've rewritten it completely.

May be we can do context (container-on-task) handling lockless?

What did you have in mind?

The example patch is attached. Fits 2.6.20-rc6-mm3.

I thought that we solved that problem by having a tmp_bc field in the
task_struct that would take precedence over the main bc if it was
non-null?

Of course, but I'm commenting this patchset which doesn't have
this facility.

OK, I can add the concept in to the example too.
