This edit renders the answer a mismash of false and true information.
We never use a temporary transaction tree to perform a read-only
operation any more.

It seems like it should be possible to make BDB repositories read-only
for read operations. RPM manages it, after all. I think the last time
I checked, RPM opens the database without an environment if it doesn't
have write access, but I don't know if I remember that correctly and I
don't know if it's safe to do so.

(We'd also have to make sure we're not creating DB transactions for read
operations. There's never any reason to do so, right?)
