Actually, there is an awful lot of code in the wild that gives
incorrect and wildly misleading error messages *because* correctly
checking the errno attribute is so rare. PEP 3151 would improve the
quality of information provided by a lot of tracebacks and error
messages without many of those developers needing to even set finger
to keyboard.

Cheers,
Nick.
