Thank you for the guidance.  I'm not familiar with Solaris innards, but
based on my reading of the Solaris afs client code, I'm guessing it handles
credentials in the same way OpenBSD does.

But it's not the credentials I'm concerned with, it's the open flags.  I
don't want to release a write-access share lock when the client still has
writers active.

However, I think I can handle this by associating open_owners with creds (as
you suggest), and then releasing them in an ordered way, read access
followed by write access.

My guess right now is that the new state model is implementable.  But only
experience will tell.

Sorry I won't be able to be at the Bakeoff next week, my wife is due to
deliver our first son any day now, and I'd like to stick around for that.
