            Bug ID: 31033
           Summary: SIP2 does not correctly handle multiple simultaneous
                    connections

If two connections are made to the SIP2 server simultaneously, the second
connection does not receive any replies until the first connection is closed. 
Here is how I reproduced the problem:

In terminal #1, use 'telnet koha.ourlibrary.com 6001' to connect to
the SIP2 server.  Send a 9300CN message to log into SIP2.  The SIP2
server sends back the expected 941 response.

In terminal #2, use telnet in the same way to connect
to the SIP2 server.  Then try sending the 9300CN message to log in.
The SIP2 does not send any response.      

In terminal #1, close the telnet connection.  Now terminal #2
receives its expected 941 message.

This problem was discovered by Lyrasis, a content provider that we are trying
to integrate with our library's Koha installation.
