> With the default heap size, sstableloader will OOM when there are roughly 25k files in the directory to load.  It's easy to reach this number of files in a single LCS column family.
> By avoiding creating all SSTableReaders up front in SSTableLoader, we should be able to increase the number of files that sstableloader can handle considerably.
