[Bug-wget] Will "-O xxx" option ALWAYS create xxx file?

        I'm using wget (v1.10.2 on Ubuntu 8.04 LTS server). Is it possible
that using "-O xxx" option xxx file is NOT created??

        I'm using wget in an cron script to periodically download some file
with "wget -qO xxx url", and I was assuming that the file xxx would be
ALWAYS created, regardless of the result of the download, and the code after
wget was assuming that. So I was not doing any test to assure xxx did really
exist. But from time to time it seems that wget fails to create the file and
the following code reports "file xxx doesn't exist" type errors...

        For instance:

        wget -qO xxx "http://..."; # any URL
        ls xxx

most of times work, but sometimes it gives an error message "ls: cannot
access xxx: No such file or directory". Does this make sense?

        Of course I can add some test for the existence of the xxx file
after wget use, but the question is: is there any situation where "wget -qO
xxx ..." could NOT create file xxx, or the file should be created in ANY

        Thanks in advance,
