write and close are sent to worker threads. For open I cannot imagine a way to parallelize the operations without rewriting tar completely. I'd be interested in both local ZFS and ZFS over NFS. Masking out the fdsyncs could be an easy enhancement. But Sun's tar doesn't do it anyway IIRC and star can be told to suppress the fdsyncs.
