+ * r1718167
+   Disable zero-copy code path for ra_local update reporters.
+   Justification:
+     Using zero-copy code path within ra_local is not safe.
+     .
+     The known and documented limitation of svn_repos_begin_report3()
+     is that with zero-copy enabled, the delta editor callbacks cannot
+     access FSFS or use Subversion caches directly.  Within ra_local,
+     we cannot be sure that arbitrary callers of our RA API, such as
+     svn_ra_do_update3(), are aware of this limitation and pass-in
+     the delta editor that doesn't access FSFS or caches.
