+5592.  [bug]           Add globally available thread_id (isc_tid_v) that's
+                       incremented for each new thread, but the old thread
+                       ids are reused, so the maximum thread_id always
+                       correspond to the maximum number of threads running
+                       at the time. This fixes the hazard pointer tables
+                       overflow on machines with many cores. [GL #2396]

                        cache. [GL #2503]
