+ * readers spin until it's back to zero, then takes the exclusive lock
+ * once the reader count has reached zero. After releasing the exclusive
+ * lock, it decrements `buffer_lock_exclusive_intent`, which, when it
+ * reaches zero again, allows readers to increment the reader count.
+ *
+ * The writer bias is necessary because we take the exclusive lock in

+ * program had a large number of threads, STW-induced pauses could be
+ * significantly longer than they have to be. Also, we emit periodic
