OK, so there is some bug. Running texpire twice, the 2nd run shouldn't
need to make any changes except when a posting has just expired, which
would be few.

The current leafnode-2 texpire may fail to restore links for
crosspostings, and the groups might then compete for the cross-posted
articles.

Does this patch improve the situation? It's a forward-port of a
leafnode-1 texpire bugfix. Apply the patch, then recompile and
reinstall, and run texpire twice. The 2nd run shouldn't print any 
"restored hard link" messages.
