> the stallReplicationWork member in FSNamesystem is accessed by multiple 
> threads without synchronization, but isn't marked volatile. I believe this is 
> responsible for about 1% failure rate on 
> TestFileAppend4.testAppendSyncChecksum* on my 8-core test boxes (looking at 
> logs I see replication happening even though we've supposedly disabled it)
