Fairly old port, never imported in the past due to some weird errors in tests, though it was always unclear whether they're test bugs, real bugs, or just something unimportant.
I thought I'd give it a go with a real program to see if this is actually anything to be concerned about - tried it as an hcache backend for mutt instead of qdbm. Seems totally fine and the difference in speed is astounding. OK to import? Tokyo Cabinet, developed as the successor of QDBM, is a library of routines for managing a simple file-based key/value database. Keys and values are serial bytes with variable length; both binary data and character string can be used as key or value. Data are organized in a hash table, B+ tree, or fixed-length array. There is no concept of data tables or data types.
