I'm not sure how/why this happens, but this can be reproduced by copying a file to a location in one process, while checking the size in another process:
Run this to copy a file indefinitely:
```
import os
import shutil
open('test').write("foo")
while True:
shutil.copy('test', 'test.file')
os.remove('test.file')
```
In the same directory run this
```
import os
count = 0
wrong_size = False
while True:
try:
size = os.path.getsize('test.file')
if size == 0:
wrong_size = True
wrong_count = count
elif wrong_size and os.path.getsize('test.file') != 0:
# We have seen the wrong size being reported, but now it's correct again
print("Got wrong file size at %dnd try, was fixed in %dnd try" % (wrong_count, count))
break
except Exception:
pass
count += 1
```
It'll (probably) fail like this:
```
Got wrong file size at 0nd try, was fixed in 1nd try
```
or more often:
```
Got wrong file size at 31nd try, was fixed in 32nd try
```
This seems to be fixed when running os.path.getsize() another time,
so we simply do that here.
