Subject: [PATCH] svn commit -m 'Backport commit 47925 committed by NathanGray.
 Handle num_rows set by application: - Don\'t overwrite num_rows setting if
 the application sets it for some reason - If num_rows is 0, don\'t get the
 initial rows server side - If num_rows is 0 and the initial rows are missing,
 trigger an update right away to get them asyncronously.' etemplate
