Here is the simple fact: if *any* process opens a BDB database and
either (1) hits a permissions problem or (2) crashes, it will leave
the BDB database wedged, in need of recovery. The process could be
apache. It could be svnserve. It could be 'svn checkout file:///'.
It could be svnadmin or svnlook or viewcvs or anything else.

Even if you set things up such that only one program ever touches the
database, you're not completely safe: it can crash too. So there is
no "good" or "bad" configuration of server processes that causes BDB
problems. If you use BDB, then the risk is always present.

That said, BDB isn't some bomb waiting to explode, either. I've used
BDB for my personal repositories for over 2 years, and never had a
wedge happen.
