IIUC this will only be used by URL, at least at first.  Is there any
other package which is likely to use it in the foreseeable "future"?
If not, then I'd recommend to name it "url-future" for now.

PS: I'd expect future-finish and future-errored to signal an error is
the future is already done-p.  And future-call should return the
future-value.
