I think it's because WebDownloadCurl is not implemented as of current

Now I have this possibly incomplete patch (attached) to implement that. 
  It works for me, but I never took the time get it reviewed/accepted, 

One thing I was forced to do is adding reference counting to 
ResourceHandleClient in order to support wasCancelled() callback.  This 
resulted in rather large amount of small changes to files where the 
client is used, so I never really liked this part of the patch.

Comments are welcome. :)

PS: the patch is not against current trunk, but r57813, so it might not 
apply cleanly. :-/  You were warned.
