Description

getColumnFamilyFromDisk starts out with

List<String> files = new ArrayList<String>();
lock_.readLock().lock();
try

{ files.addAll(ssTables_); Collections.sort(files, new FileNameComparator(FileNameComparator.Descending)); }

finally

{ lock_.readLock().unlock(); }

this is silly, we should really keep the list sorted instead of re-sorting for each read.
