* Upgraded to Berkeley DB 4.1.25 and do not synchronously flush the
...
log on commit. This means that there is a small change that some
transactions may be rolled back in case of a system crash, but this
should not be a problem (it merely might cause some expression
realisations to be rolled back), and it vastly improves performance.
* Upgraded to ATerm 2.0.5 (which also includes Armijn's 64-bit
patches).

* Get rid of identifiers since they are redundant now. This greatly
...
simplifies stuff.
* The format of Nix expressions and the database schema changed
because of this, so it's best to delete old Nix installations.

* Enclose most operations that update the database in transactions.
...
* Open all database tables (Db objects) at initialisation time, not
every time they are used. This is necessary because tables have to
outlive all transactions that refer to them.

* Use a more reasonable log file size (256 KB instead of 10 MB).
...
* Checkpoint on exit.

* Started using Berkeley DB environments. This is necessary for
...
transaction support (but we don't actually use transactions yet).

* Do sync the database, since not doing so caused database changes not
...
to reach the disk at all. Looks like a bug.

* Don't sync the database on close. This was killing performance.
...
(Of course, the real problem is that we open the database for
*every* operation; we should only open it once. And we should use
transactions.)

* For debugging: `nix --verify' to check the consistency of the
...
database and store.
