  KNOWN BUGS
  ==========
  
 -* What happens in the following scenario:
 -    1) We are reading an AOF file.
 -    2) SETEX FOO 5 BAR
 -    3) APPEND FOO ZAP
 -    What happens if between 1 and 2 for some reason (system under huge load
 -    or alike) too many time passes? We should prevent expires while the
 -    AOF is loading.
  * #519: Slave may have expired keys that were never read in the master (so a DEL
    is not sent in the replication channel) but are already expired since
-   a lot of time. Maybe after a given delay that is undoubltly greater than
+   a lot of time. Maybe after a given delay that is undoubtably greater than
    the replication link latency we should expire this key on the slave on
    access?

 -DISKSTORE TODO
 -==============
 -
 -* Fix FLUSHALL/FLUSHDB: the queue of pending reads/writes should be handled.
 -* Check that 00/00 and ff/ff exist at startup, otherwise exit with error.
 -* Implement sync flush option, where data is written synchronously on disk when a command is executed.
 -* Implement MULTI/EXEC as transaction abstract API to diskstore.c, with transaction_start, transaction_end, and a journal to recover.
 -* Stop BGSAVE thread on shutdown and any other condition where the child is killed during normal bgsave.
 -* Fix RANDOMKEY to really do something interesting
 -* Fix DBSIZE to really do something interesting
 -* Add a DEBUG command to check if an entry is or not in memory currently
 -* dscache.c near 236, kobj = createStringObject... we could use static obj.
