on a previously reliable machine. That connection has been stuck for
9 hours so it does not time out, etc. - and the distcc run that goes
over that connection is stuck as well.


interestingly enough, I think I'm seeing something very similar to this
with the claws email client; as of 2.6.26-rc3 (sorry, didn't run
earlier ones because they broke my wireless) claws gets "stuck" once in
a while, really stuck, when talking to the imap server.....
It seems to happen a little less frequently when running under strace,
but it still happens, so that could just be a timing thing.
