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

[Antoine Pitrou]

Antoine Pitrou added the comment:

There are actually several issues here:

* collection of globals at shutdown is wonky: you should add an explicit "del a,f; gc.collect()" at the end of the script

* order of tp_clear calls, or another issue with TextIOWrapper: if you open the file in binary mode ("f = open('...', 'wb'); f.write(b'bar')"), the data gets flushed during the GC run
