 An important non-intuitive issue is that code can be delayed at
 any point for any amount of time.
 Consider a producing and a consuming thread that communicate using
-a global struct with a timestamp ``t'' and integer fields ``a'', ``b'',
-and ``c''.
+a global struct with a timestamp \qco{t} and integer fields \qco{a}, \qco{b},
+and \qco{c}.
 The producer loops recording the current time
 (in seconds since 1970 in decimal),
-then updating the values of ``a'', ``b'', and ``c'',
+then updating the values of \qco{a}, \qco{b}, and \qco{c},
 as shown in \cref{lst:app:questions:After Producer Function}.
 The consumer code loops, also recording the current time, but also
-copying the producer's timestamp along with the fields ``a'',
-``b'', and ``c'', as shown in
+copying the producer's timestamp along with the fields \qco{a},
+\qco{b}, and \qco{c}, as shown in
 \cref{lst:app:questions:After Consumer Function}.
 At the end of the run, the consumer outputs a list of anomalous recordings,
 e.g., where time has appeared to go backwards.
