+			 * A concrete case to illustrate why we might lock up if
+			 * we do not consume other_info:
+			 *
+			 *   We have 4 threads, all accessing the same address
+			 *   (or matching address ranges). Assume the following
+			 *   watcher and watchpoint consumer pairs:
+			 *   write1-read1, read2-write2. The first to populate
+			 *   other_info is write2, however, write1 consumes it,
+			 *   resulting in a report of write1-write2. This report
+			 *   is valid, however, now read1 populates other_info;
+			 *   read2-read1 is an invalid conflict, yet, no other
+			 *   conflicting access is left. Therefore, we must
+			 *   consume read1's other_info.
+			 *
+			 * Since this case is assumed to be rare, it is
+			 * reasonable to omit this report: one of the other
+			 * reports includes information about the same shared
+			 * data, and at this point the likelihood that we
+			 * re-report the same race again is high.
