+\subsection{Non-atomic (``Thread-Local'') Invariants}
 
 Sometimes it is necessary to maintain invariants that we need to open non-atomically.
 Clearly, for this mechanism to be sound we need something that prevents us from opening the same invariant twice, something like the masks that avoid reentrancy on the ``normal'', atomic invariants.
