It depends.
If the per-thread variable was accessed only from its thread,
- and never from a single handler, then no.
+ and never from a signal handler, then no.
Otherwise, it is quite possible that \co{ACCESS_ONCE()} is needed.
We will see examples of both situations in
Section~\ref{sec:count:Signal-Theft Limit Counter Implementation}.
