[Seaside] Does DabbleDB use a database?

[Welch, Ronald P (US SSA)]

I am not so sure that Dabble's profile is all that "odd" as you
put it. I think that persistence mechanism you guys have come up
with could be generally useful in a lot of scenarios. I for one
would very much like to understand the gory details of how you
went about attacking and solving the problem of persistence
in Dabble.

Nothing third-party -- we've written all the transactional/ 
checkpointing/etc code for this ourselves, as nothing else did what  
we needed.. (not surprising as Dabble has a bit of an odd profile).
