I don't understand what you're saying here. Are you saying that if we
include the get_remaining API in serf 1.4.0, that you'll make svn 1.9
If there are no short term plans to start using it, I'd remove it from
the 1.4 release and keep it on trunk for 1.5 or later.

Ok, the lookup is indeed quite expensive.

I'll see if I can have some time in the coming week to work on my proposal.
