Somebody took "world" write permission on /tmp away; I don't know 
whether this was intentional - I have restored them for a moment.

The script actually has two errors: it is not os.sleep, but time.sleep
(so it would only try one time, not ten times); plus (and I'm glad
you did not catch that, either :-) the finally block is always executed,
even if the file was not created, and even if the function is left
through return.

I've fixed the script, however, if somebody takes away o+w on /tmp
again, it will mean that the caching silently stops.
