+    if (lsn > PageGetLSN(page))
+    if (lsn >= PageGetLSN(page))
+    if (lsn <= PageGetLSN(page))
+            if (max_lsn < this_lsn)

My only comment here would be that I would like it much better that the
code always use the same operators, and as we read from left to right,
that we pick < and <=.
