> intermittant exceptions in TestConcurrentMergeScheduler

> The TestConcurrentMergeScheduler throws intermittant exceptions that
> do not result in a test failure.
> The exception happens in the "testNoWaitClose()" test, which repeated
> tests closing an IndexWriter with "false", meaning abort any
> still-running merges. When a merge is aborted it can hit various
> exceptions because the files it is reading and/or writing have been
> deleted, so we ignore these exceptions.
> The bug was just that we were failing to properly check whether the
> running merge was actually aborted because of a scoping issue of the
> "merge" variable in ConcurrentMergeScheduler. So the exceptions are
> actually "harmless". Thanks to Ning for spotting it!
