presumably you have readers on different machines accessing the
index over NFS, and then one machine that does the writing to that

the deletion of the file, and the held-open file handles, happen
through a single NFS client, then it emulates delete-on-last-close

Test to be sure though!

The bigger picture here is NFS-safety. When I run a search, I hand off the
search results to another thread so that they can be processed as necessary --
in particular so that they can be JOINed with a SQL DB -- but I don't want to

Is there a direct way to ask an IndexReader what segment it is pointing at?
That would make implementing custom deletion policies a LOT easier.
It seems like it should be pretty simple -- keep a list of open IndexReaders,
track what Segment files they're pointing to, and in onCommit don't
When implementing a custom IndexDeletionPolicy, is it sufficient to just use
the segments filename (returned by IndexCommitPoint.getSegmentsFilename()) to
compare CommitPoints to see if they are equal?
I've looked at the code in SnapshotDeletionPolicy and it works by keeping a
pointer to the
