I don't think Wikipedia can explain implementation details of the LCL/RTL..

But if TCriticalSection uses a MUTEX (which in fact is a FUTEX as (on 
Linux) it uses pthreadlib mutex function from LibC, which automatically 
uses FUTEX if available in the underlying arch, otherwise fallback to 
MUTEX) (and I believe it is implemented this way) same blocks all at the 
start of the section independently from the core they run on, and thus 
no concurrent access can happen.
