Why do we need to differentiate a thread stack from a process stack?
If someone really wants to know, the main stack is the last one since
it doesn't look like mmap allocates anything above the stack right
now.

I like the idea of marking all stack vmas with their task ids but it
will most likely break procps. Besides, I think it could be done
within procps with this change rather than having the kernel do it.
