-VM TODO
-=======
-
-* Use multiple open FDs against the VM file, one for thread.
-* Check what happens performance-wise if instead of creating threads again and again the same threads are reused forever. Note: this requires a way to disable this clients in the child, but waiting for empty new jobs queue can be enough.
-* mmap the swap file.
-* Use just a single IO Job to swap out a key, and add a mutex so that pages in the page table can be marked as used and scanned from the thread itself.
+DISKSTORE TODO
+==============
+
+* 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.
+* Use a mutex to log on the file, so that we don't get overlapping messages, or even better make sure to use a single write against it.
+* 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
