Execution in order only makes sense when there is another thread that 
relies on this order.

So if both threads use the same critical section for accessing all 
variables that an ordering is necessary with, the actual ordering used 
completely within the critical section in fact is irrelevant as no other 
thread can get in the way at that point. So the high level Posix 
interface that is provided as TCriticalSection in the RTL/LCL should be 
workable (but not high performance).
