Hello.

In pipeline patch test530 was changed but it does not work as intended.

<servercmd>
pipe: 1
pipe: 3
</servercmd>

I expected server to wait for first request, send first response. And
then wait for 3 requests to come before sending next response. But
only first pipe instruction was really used. Test does not fail for me
when run once. But it fails if I run "./runtests.pl 530 530". And
sniffer shows that it is really broken.

I think this leads to random failures reported by Guenter Knauf.

Fix for the test is attached. Instead of using pipe servercmd I split
responses into separate <dataN> sections and for requests which should
be pipelined send only part of response is sent.

Regards,
