Subject [jira] [Commented] (SOLR-2861) transaction log / realtime-get failures

Update: I think I may have found one logic bug in solr - a hard commit reopen can go back
in time since it doesn't use the writer to repoen. For example Thread1: commit() Thread2:
reopen(writer) Thread1: reopen(without_writer). That last reopen will reopen at the point
of the commit, going back in time if updates happened in between.

Actually, I don't think this is true.  AFAIK, once you call openIfChanged(reader,writer) it
doesn't matter if future calls are just to openIfChanged(reader) since reopening an NRT reader
will always result in another NRT reader?
