Fix deadlock waiting for read or write on closed connection.
If the system is suspended then it may not realise that a TCP connection has
been closed, while waiting for data to arrive on it. We didn't used to apply
a timeout to this read operation. Now we use the connection's default timeout
on all read and write operations. Network operations that don't pass a timeout
will be logged with a backtrace, so that they can be fixed.
