[iBorrow] Duplicate OCLC Requests

This is a brief OCLC update.  
Since the latest build, URSA has found a new way to submit duplicate
requests to OCLC.
I'll summarize it below.
The good news is that SirsiDynix has found the cause of the problem,
created a solution, and will fix it on the RSS server some time today.
You may find some duplicate requests on OCLC right now, if we have OCLC
listed as your LOLR in your URSA setup.

Here's how the error happens.
If OCLC is your LOLR, URSA will automatically send a request to OCLC, if
it can find no available copies locally.
An URSA-to-OCLC request goes through several servers:  URSA to Gateway
to RSS to OCLC, then back to RSS to Gateway to URSA.
Each one sends a message to the next one and waits for 45 seconds for an
acknowledgement response.  
If it does not get a response in that time, it assumes the message did
not go through.

In this case, the message got all the way to OCLC, but the response did
not get all the way back.  So, OCLC got the request automatically.  But
URSA did not know OCLC had the request, so it left the request in your
Mediate Borrowing work space.  Some of you manually sent some of those
requests on to OCLC.  That's how the duplicates got there.

The timing problem occurred in the RSS server, and will be fixed there
some time today.
