Heh. Just to be clear:
The reason we keep saying that is so that poor Sleepycat Software
(maker of BDB) doesn't get blamed for a problem in Subversion's code.
BDB as delivered by Sleepycat is solid, one just has to use it in the
right way. We didn't, we got burned. However, Sleepycat's reputation
shouldn't suffer... which is why we make those posts.

Yup. We are well aware, and we are working on it, with help from
Sleepycat (it's a tricky architectural problem). In the meantime,
making FSFS the default repository storage back end in 1.2 will
hopefully make the problem go away for 99% of users. Those who choose
not to use FSFS will be doing so consciously now.
By the way, I know of no evidence that FSFS is slower. Not sure what
less "high tech" means -- but trust me, it's never been the basis for
any technical decisions in Subversion :-).
