As Victor said, the `time.sleep(1.0)` might lead to Heisen failures. I am not
sure how to write proper strong synchronization in this case but we could
instead go for something intermediate such as the following pattern:
...
p.terminate()
p.wait()
for i in range(60):
try:
shared_memory.SharedMemory(name, create=False)
except FileNotFoundError:
# the OS successfully collected the segment as expected
break
time.sleep(1.0) # wait for the OS to collect the segment
else:
raise AssertionError(f"Failed to collect shared_memory segment
{name}")
What do you think?
