I don't think the symptoms are consistent with this, at least from what
I understand.  It seemed from Andrew's observations that the data put
into a session from earlier transactions was lost too (not just the data
put in during the transaction during the request which invoked the error
handler, nor just the data put into the database via the transaction
which was running concurrently with the aborted transaction).  It was as
if the internal data structures of the session data container were
becoming out of sync.  I don't have a particularly good explanation for
this behavior.
