If you are talking about the API, the current head for SYSIO is
thread-safe for all but initialization, mount, unmount, and shutdown.
Don't think it works for liblustre at present, but rklundt at sandia.gov is
currently doing a port, maybe done already.

Re-entrancy is to be supported some time in 2010.

But... I thought SUN had dropped support for liblustre entirely? Did I
miss something?
