slave dbh's don't seem to get validated

[Steven Shou]

Hi all,

I'm running MogileFS with MySQL on one master and many slaves.   
Everything works great until connections to the slave dbs timeout for  
the idling query workers.  Then, all get_paths commands would return  
'unknown_key' which is not what I want.

Is there any better way that I'm not aware of, or are changes below  
fine?

From
sub validate_dbh { Mgd::get_store()->recheck_dbh }

To
sub validate_dbh {
	my $store = Mgd::get_store;
         $store->recheck_dbh;
         $store->read_store()->recheck_dbh if $store->is_slave;
}
