+# This testfile is in sections because the goal is to verify the behavior
+# when a reindex occurs during an active transaction, both as a result of the
+# transaction's actions as well as the result of the HEAD's actions. In order
+# to keep this test quick, it's easier to restart and hit the known
+# reindexing at 17 keys vs. attempting to hit the second-level reindex which
+# can occur as early as 18 keys and as late as 4097 (256*16+1) keys.
