I don't think it's quite as bad as that. The S3 format is
string based, so easily detected by the terminating null.
The S4 format contains a bunch of extra stuff that S3
doesn't support or maintain (birth times in NTTIME
format etc) so we could cope with both - but I'm expecting
the POSIX vendors to add birthtime (as *BSD has) with
ns timestamps so we can just use the filesystem for

As I recall, both patches were originally done by you, the
early S3 one being you did really easy to integrate
with existing code (not blaming you here, it's just funny :-).

Wish we'd have used a slightly different name though,
but there you go :-).

All Volker's change is doing I think is storing the
S3-specific one in a tdb, we have to map between the
two anyway so it doesn't make things any worse than
they already are.
