I have a known outstanding bug to do with deadlock from FKs that cross
(i.e. A has an FK that references B, and B has an FK that references A).
The solution to this could be mildly complex, but I have an outline of
it in my head. Workaround: recreate the failed FK at the end of the restore.
The only other reported problem is the one on Unixware to do with
closing the archive. I haven't been able to reproduce it on Linux or
Windows, the two platforms I test on, although it might be fixed by the
patch I just applied.
cheers
