 indefinitely, a proper fix will additionally need to make the registration
 asynchronous. It might be too late to ship the full fix in 0.90, though.

 Not sure if this fix is safer than rewriting it to use gio, have been
 reading about the different hacks that people have used to overcome this
 xmlrpclib limitation and looks like they depend on non-API stuff that
 could (and does) get broken between releases.

 I think using xmlrpclib.dumps and xmlrpclib.loads together with gio could
 be simple enough, we are already using gio for async http:
