XTHREAD is just another way of getting References data; it's pretty much
obsolete now in favor of the more standard XOVER command to get overview
data.  Check the News::* modules on CPAN; someone else may have written a
module that will do threading from References headers by now.

Threading isn't done on the server; it's entirely in the client.  So it's
a matter of finding a client library that knows how to do this.
