The call to self.ts.addInstall():
                self.ts.addInstall(hdr, (hdr, rpmfile), txmbr.ts_state)

I don't know if it's easy to see this without printf()'s in the
Berkeley DB source code. Running strace on the process should also
show multiple opens of db.###. You'll see several opens followed by
several mmap() calls. Then, you see them again after the call above.
In between, the initial mmap()'s have not been munmap()'ed because
self.read_ts.ts and self.read_ts are still active. They become
inactive in closeRpmDB() but that doesn't occur until yum ends.

Well, in this case, both open the __db.### environment files.

rpm-4.2.4. I don't think the version matters though.
