New submission from Antony Lee <anntzer....@gmail.com>:
In a first Python process, repeatedly create and delete a file:
from pathlib import Path
while True:
Path("foo").touch(); Path("foo").unlink()
In another process, repeatedly check for the path's existence:
from pathlib import Path
while True: print(Path("foo").exists())
On Linux, the second process prints a random series of True and False. On
Windows, it quickly fails after a few dozen iterations (likely
machine-dependent) with
PermissionError: [WinError 5] Access is denied: 'foo'
which is actually raised by the stat() call.
I would suggest that this is not really desirable behavior?
