Tom a95b726fd8 Kernel: Fix race causing modifying a Process to fail with a panic 
The ProtectedDataMutationScope cannot blindly assume that there is only
exactly one thread at a time that may want to unprotect the Process.
Most of the time the big lock guaranteed this, but there are some cases
such as finalization (among others) where this is not necessarily
guaranteed.

This fixes random panics due to access violations when the
ProtectedDataMutationScope protects the Process instance while another
is still modifying it.

Fixes #8512
