I'd prefer to address this upstream rather than as a Debian-specific 
patch (see also: the forwarded report above).

Would this revert be considered (by Python upstream) to be a correct 
solution, or a workaround, or what? Is there a porting guide available 
that would clarify what the most appropriate change is?

ebecd174 was an attempt to follow what, at the time, I believed was 
upstream best-practice. Perhaps I was wrong about that, or perhaps 
best-practice has changed - but I'd prefer to know which is applicable.

Thanks,
