It depends where you put things. Nothing stops the TSS and inode map
being at the end of the task structure. So you allocate a new task
structure of the desired size. The only problem there is Linus 8K hack
and the fact a 16K block is really pushing things harder in the current
mm problems. You have to do this in advance too - trying to swap the
kernel stack of a task is not a sane proceedure.

I'll keep thinking
