What the heck...? I am 100% confident it passed all of the 39 self tests
before I shipped the patch, but now it doesn't. I'm wondering if I ran
the check in the right directory or just thought I did when I in fact
did not.

Anyways, it doesn't work now, and there are still bugs in the database
layer that goof up. I inserted debug statements and got "invalid
mode".

I'm wondering if QDBM might only like transactions in "writer" mode
databases but not in "reader" mode. Probably around DB creation and such.
