+run code in a memory context not associated with a process. The thread schedular loads CR3 with `KTHREAD->ApcState->Process->DirectoryTableBase`. You can make
+KPROCESS structure and change DirectoryTableBase to your new address space. DirectoryTableBase contains a CR3 value just FYI... its not just a physical address...
