Re: put hangs

Ok, I did some more tests.

put("1"*12105, '/tmp/tmpfile.txt')

works, and

put("1"*12106, '/tmp/tmpfile.txt')

does not work. So it looks like my threshold is about 12k. I don't
know what that means, or why it is happening. I'm running Ubuntu Gutsy
on the client side, and Ubuntu Dapper on the server side.
