[issue17852] Built-in module _io can loose data from buffered files at exit

[Armin Rigo]

Armin Rigo added the comment:

I hate to repeat myself, but if the C standard says "files are flushed at exit"; if Python 2 follows this standard; and if Python 3 follows it most of the time but *not always*...  then it seems to me that something is very, very buggy in the worst possible way (rare data loss).
