I sincerely hope it is fixed. Mathematically I don't feel I
can ascertain it's gone. I have, however, dramatically
shortened the window in which it might occur -- IF my theory
on how it comes about is correct.

The fact that apparently you were able to expose it using
one client only while I only ever encountered it using two
clients working on the same patient somewhat bolsters my
theory of unfortunate timing during concurrent operations
triggered by backend updates.

At the end of the day I have a nagging feeling that the root
of the evil is non-locking access to middleware variables ...
