I guess frequent deletions and lack of space recovery are the problem with btrees?

I did a quick ports search and came up with databases/ruby-bdb1.  I don't grok ruby
but I've telling myself I should learn [sigh].  I don't know if this has a simple
API or not; I'll take a look but I suspect it is probably overkill.

If this doesn't meet your project's needs I'll try coding something up in C.  I
imagine we'll need some tools written in C at some point anyhow.

Well, we'll see about how much help I can be; but I'll try.  It's your project
so let me know what you need or don't need/want
