IW#nrtIsCurrent retruns true if changes are in del queue but not in
bufferedDeleteStream yet
--------------------------------------------------------------------------------------------
Key: LUCENE-3546
URL: https://issues.apache.org/jira/browse/LUCENE-3546
Project: Lucene - Java
Issue Type: Bug
Components: core/index
Affects Versions: 4.0
Reporter: Simon Willnauer
Fix For: 4.0
spinnoff from SOLR-2861 - since the delete queue is not necessarily applied
entirely on each request there is a chance that there are changes in the delete
queue but not yet in buffered deletes. this can prevent NRT readers from reopen
when they should... this shows the problematic code:
