a thread that's already on a runqueue.

vm: replace vm-region with address-space
...
address-space is a non-recursive data structure, which contains a flat list of vm_areas representing
mapped vm-objects.
userspace programs can no longer create sub-address-spaces. instead, they can reserve portions of
the address space, and use that reserved space to create mappings.
