It seems essentially impossible for the driver to do this reliably,
since it has no clue how much data any one query will return.

How about instead thinking in terms of not filling the driver->server
channel? You have a good handle on how much data you have sent (or at
least you could keep track of that), and if you bound it to 64K or so
then you should be safe. Perhaps the limit ought to be easily
configurable just in case, but at least you'd be measuring something
measurable.
