dictionaryWithContentsOfURL is a pretty simple-minded way to check a remote
URL, and it's probably synchononous (explainint the hang). I use NSTask and
'curl'; this gives a lot of control, it's asynchronous, and if there's an
error/timeout you get back a useful result. (There are other ways but I find
this particularly easy.) m.
