The only thing in the Directory API which is required to be atomic and 
that's used to implement commit, is renameFile().  This is called when 
all IndexOutputs have been closed.  Immediately after the rename is 
completed is the appropriate place to commit a transaction.  Perhaps 
this should be more explicit in the API...
