Simon Willnauer updated LUCENE-4147:
------------------------------------
Attachment: LUCENE-4147.patch
I feared that this is gonna hang at some point. I moved the docWriter abort /
close out of the sync block in IW rollbackInternal and beasted the new test +
all other tests for hours now. I think this is fine to move that out, no need
really to keep the IW lock since we already have the commit lock in our hands.
I didn't see a failure so far.

> rollback should never throw this exception, as it documents it clears any
> pendingcommits.
> but it calls closeInternal outside of any sync block, so it looks like there
> is a race here.
