History
Andreas Kling 1d08b671ea Kernel: Enter new address space before destroying old in sys$execve() 
Previously we were assigning to Process::m_space before actually
entering the new address space (assigning it to CR3.)

If a thread was preempted by the scheduler while destroying the old
address space, we'd then attempt to resume the thread with CR3 pointing
at a partially destroyed address space.

We could then crash immediately in write_cr3(), right after assigning
the new value to CR3. I am hopeful that this may have been the bug
haunting our CI for months. :^)
