But read the following comment about sendSynchronousRequest in

is necessary in the calling thread in order to perform a
synchronous load. For instance, the calling thread need not be
running its run loop."
Sounds like threadsave to me!
I disagree, I don't think it says anything like that.
Among the links that I re-send to Cocoa-Dev from time to time, this
is probably in the top-five:
<http://developer.apple.com/documentation/Cocoa/Conceptual/
Multithreading/articles/CocoaSafety.html>
I don't see any NSURL*** class in these lists, so we would probably
have to assume that it's not safe to call the URL loading system from
multiple threads at the same time - actually, it might not even be
safe to make calls from anything but the main thread.
