> For non-mmap'ed I/O on Windows, using nio channels will give us substantially more flexibility w/regards to renaming and moving files around while writing them.  This change in conjunction with CASSANDRA-4050 should allow us to remove the Windows bypass code in SSTableRewriter for non-memory-mapped I/O.
> In general, migrating from instances of RandomAccessFile to nio channels will help make Windows and linux behavior more consistent.
