 Datastores:
 * implement sqlite-based sqstore/datastore service
-  + implement service (datastore + talks to plugin)
-  + get testcases to pass
+  + complete service implementation and improve testcase coverage
 * implement sqlite-based dstore services
   + design API
   + implement library (talks to service)

  * Target datastore size (in bytes).
- * <p>
- * Example impact of total size on the reported number
- * of operations (insert and delete) per second (once
- * roughly stabilized -- this is not "sound" experimental
- * data but just a rough idea) for a particular machine:
- * <pre>
- *    4: 60   at   7k ops total
- *    8: 50   at   3k ops total
- *   16: 48   at   8k ops total
- *   32: 46   at   8k ops total
- *   64: 61   at   9k ops total
- *  128: 89   at   9k ops total
- * 4092: 11   at 383k ops total (12 GB stored, 14.8 GB DB size on disk, 2.5 GB 
reported)
- * </pre>
- * Pure insertion performance into an empty DB initially peaks
- * at about 400 ops.  The performance seems to drop especially
- * once the existing (fragmented) ISAM space is filled up and
- * the DB needs to grow on disk.  This could be explained with
- * ISAM looking more carefully for defragmentation opportunities.
- * <p>
- * MySQL disk space overheads (for otherwise unused database when
- * run with 128 MB target data size; actual size 651 MB, useful
- * data stored 520 MB) are quite large in the range of 25-30%.
- * <p>
- * This kind of processing seems to be IO bound (system is roughly
- * at 90% wait, 10% CPU).  This is with MySQL 5.0.
