+ * r1666965
+   Reduce 'the lag' of the first svn log results over mod_dav.
+   Justification:
+     A slow svn log makes users call Subversion slow. This fixes the
+     perceived performance problem by no longer optimizing just for
+     obtaining all the results fast, but also for obtaining the first
+     result fast.
+     .
+     Just the perceived slowness of common svn log operations might
+     make users switch to a DVCS, while this slowness is just a buffering
+     to make the total set of results come in faster. But I don't think
+     there are that many users that really wait for all results of
+     .
+     $ svn log -q ^/subversion/trunk
+     .
+     This currently takes > 10 seconds before the first result using
+     the EU mirror for me. With --limit 1 (best comparison with post-patch)
+     that would be 0.2 seconds.
