------------------------------------

    Resolution: Won't Fix

Sorry if this spam's things, however it's unlikely that I'll work on these.

> Doing a small patch to make sure things don't break in a big
> way, we'll use RRWL replacing some of the global synchronized
> locks in IndexWriter. 
> We'll read lock during operations that for example delete from a
> segment, and gwrite lock when we're changing the main segment
> infos collection (i.e. we're swapping in new segments after a
> merge, or flushing a new segment). 
> I want to implement this, see if any tests break. 
> Spin off from LUCENE-2047.
