Sure; I'm only looking at locking things between the time I get a copy
of the bug for modification, and the time I write one back - a matter of
a second or two.

Sync errors of the sort you describe are easier to spot using timestamps.

The updates from the remote system arrive periodically in one big bunch,
as a set of "current states", not a set of "deltas"; there are no
conflicts among them. (I.e. any problems at the other end have already
been sorted out.)
