Hi Bill,
Is it possible that there are objects that aren't in _any_
EditingContext? Created but not inserted? That can cause some really
crazy stuff.

Hello all,
We're seeing this really weird behaviour in our applications from
time to time. At this point, we haven't found any way to reproduce
it - it's intermittent, but when it happens, fetches from/saves to
the database all bail and the application needs to be restarted.
Our suspicion is some sort of a race condition, but from what I can
see from poking around inside EOF this stuff is supposed to be
single threaded. What's strange is that all of the objects involved
are in the _same_ editing context.
This is a Wonder-ized application running as a servlet with
concurrent request handling and auto-locking turned on.
