Hello!
I've hit a strange problem that I reduced to the following test case:
* Run several python processes in parallel that spin in the following loop:
while True:
if os.path.isfile(fname):
with open(fname, 'rb') as f:
f.read()
break
Besides anything else, I would consider adding a minimal sleep in the loop.
* Then, run another process that creates a temporary file and then
renames it to the name than other processes are expecting
* Now, some of the reading processes occasionally fail with "Permission
denied" OSError
