> The test was using NRTCachingDirectory, but the OOME happens because
> CompoundFileWriter's getOutput fails to pass down the incoming IOContext.
> IndexWriter has properly set up the IOContext for flush, put a huge file size
> in there, but by the time NRTCachingDirectory saw it, it was 0 bytes, and
> then many 100s of MB proceeded to be written into the RAMFile.
