/**
 * We use a ReferenceQueue to manage deleting files that have been compacted
 * and for which no more SSTable references exist.  But this is not guaranteed
 * to run for each such file because of the semantics of the JVM gc.  So,
 * we write a marker to `compactedFilename` when a file is compacted;
 * if such a marker exists on startup, the file should be removed.
 *
 * This method will also remove SSTables that are marked as temporary.
 *
 * @return true if the file was deleted
