> In a cluster with a lot of small files, we encountered a case where fsck was 
> very slow. I believe it is due to contention with many other threads reading 
> / writing data on the cluster.
> Sometimes fsck does not report any progress for more than 60 seconds and the 
> client times out. Currently the connect and read timeout are hardcoded to 60 
> seconds. This change is to make them configurable.
