* Do not use Tokyo Tyrant in a production setting without replication. Make frequent backups.
* as far as I can tell, you have to call sync manually.. if you don't and the writes fill up your memory, writes slow to a crawl and there's a chance that the db file will corrupt when you finally sync or terminate the daemon.
* if you run out of disk space, your db will become corrupt
* if you accidentally start two instances of tokyo tyrant on the same file, it may become corrupt
* If you're using the hash db, be sure to tune the bnum param. If you're working with a lot of data, tune xmsiz as high as possible.
* 'putlist' stores duplicate records for b+ tree, which may or may not be what you expect.
* "bulk loading" the db is much much slower than mysql's select data infile
