Andreas Kling 8ed06ad814 Kernel: Guard Process "protected data" with a spinlock 
This ensures that both mutable and immutable access to the protected
data of a process is serialized.

Note that there may still be multiple TOCTOU issues around this, as we
have a bunch of convenience accessors that make it easy to introduce
them. We'll need to audit those as well.
