Re: put hangs

Adding "set :synchronous_connect, true" fixed by put hang, but I also
noticed that, for me, put would only hang with "large" files. I kept
repeatedly trying to put the same file, and as I whittled it down it
would finally go through. Maybe that will help someone debug. I didn't
spend enough time to figure out exactly what the threshold is, because
the :synchronous_connect option worked for me, but the full file I was
trying to send was only 196k, so it's a low threshold what ever it is.
