Also, the new upstream DLM has the ability to be configured in a
client/server model arrangement, where all lock requests go to specific
DLM nodes rather than being resolved locally.  You can tune the usage to
your configuration and still have dedicated lock manager servers if you
choose.  This capability makes GuLM redundant with the DLM functionality
and doesn't make sense to continue to port GuLM forward and support.  

I think Dave Teigland has documented how to do it in either previous
mailings or on the website, will let him comment with the details.

Thanks
