 BEFORE REDIS 1.0.0-rc1
 
- * SPOP man page
  * Add number of keys for every DB in INFO
- * check 'server.dirty' everywere. Make it proprotional to the number of objects modified.
  * Cover most of the source code with test-redis.tcl
  * Remove tmp-.... files when saving child exits in the wrong way, to do so use tmp-pid.rdb as filename so that the parent can rebuild the file name just from the child pid.
