not sure what your commit is doing exactly. but there is a bug somewhere i guess.

I've had a fix sitting on my hard drive for a year lol, sorry. The current master seems to do fine.

The change was necessary because there's more than 1 FD on the client side now - to support forwarding multiple ports.
