Workarounds are in order.  There's other people attempting to solve  
this problem for Lucene, and I'm going to focus my efforts  
elsewhere.  If a solution arises, we can port it.

Wrapping your Searcher constructor call in an eval is kind of ugly,  
but it's an easy workaround.  How about this?

     my $searcher = eval {
             KinoSearch::Searcher->new(
                 analyzer => $analyzer,
                 invindex => $invindex,
             );
         };
     if ($@) {
         warn("Failed to create Searcher (will retry): $@");
         sleep 1;
         $searcher = KinoSearch::Searcher->new
             analyzer => $analyzer,
             invindex => $invindex,
         );
     }

I would hope that 1 second is enough for any NFS cache issues to  
resolve themselves.  If not, we'll know about it from the logs.  If  
we see a Searcher constructor fail twice in a row, we investigate  
further.
