I'm running out of time, so I'm going to dump what I've got:

* I already moaned about gotos.

* Why does the patch change the set_trace test in generator.ml?

* Don't just comment out xread: remove it. These pile up over time and
make the code unreadable.

* Don't put a usleep() in read_log_message_or_eog. I understand your
argument, but in this case the cure is worse than the disease. If you
think about it, the patch back into the main loop and back here is
actually very short, and very cheap. As well as being ugly as sin, this
usleep is only going to slow it down.

* guestfs__send and send_file_chunk both leak msg_out in the non-error
case.

I'll continue until I have to go.

As discussed on IRC:

In recv_from_daemon, why not allocate buf_rtn fully once its size is known?

recv_file_data
    leak buf if return == -1 (e.g. second read in recv_from_daemon fails)

receive_file_data
    leak buf if return == -1

Apart from that, I think this patch is the right direction, it clearly works and should get as much testing as possible.

ACK.

Matt
