I agree too. I think there would certainly be no argument with taking
a patch that did only that. (Except that it makes the option list
even more ridiculously bloated.)
I think a better fix is to transfer directories one by one, pipelined,
rather than walking the whole tree upfront. This will take a protocol
change and a fair amount of work, but I think it is possible. If we
can get it to just work faster transparently that is better.
