What gets called from other functions? What causes the loop if that is
removed?

You can't ever check whether remote locations are permanently gone,
since there might be temporary issues (network down, no network) that
causes it to seem gone when it is not.

Furthermore, we don't want to do blocking i/o, so even a non-working
check would be much more complicated than just a call. And, as I told
you in my last mail, the nautilus_file_get_existing call is totally
wrong here. It doesn't in any way test whether a file exists.
