I think I did it that way because there were no libraries available at the time - just the original djb implementation, which wasn't really fitted as a library. But there was a good spec so I implemented from that. Cdb was a good lookup system and for the sort of ISP stuff I was doing at the time it was a good order of magnitude faster, needed no locking and has atomic updates at the cost of having to regenerate the whole file. Buy me a drink sometime and I'll tell you about the semi-writable version....
