I don't think this actually ever gets called.

Yeah, but if it ever does we will do the right thing. :)

Is this the right thing?  Can we be guaranteed that all network threads have
been killed at this point?  I'm not sure we can be, so we may still be calling
into GURL functions, at least destructors.

Seems safer to just leak here.

Done.
