This whole discussion is a very good one.  My opinion is that however
possible, software should be designed to encourage orderly exiting and
termination of transactions.  As such, I think that this proposed enhancement
to QCTerm is a good request.  By disallowing at least one form of 'bad' user
behavior, some problems can be prevented.  Not all, but some.

Nothing in software is going to be able to handle a yanked power plug (UPS
units for every desk?), a Windoze crash/freeze (never happens...), a
cut/pulled cable, etc, etc, and more etc. Hopefully these are all unplanned
accidents and somehow, application software should be designed so that no
data corruption can occur at any point in any transaction.  Many if not most
applications just are not that robust though.
