These are large tables:
```
$ dolt sql -q "select count(*) from actor"
+----------+
| count(*) |
+----------+
| 290054 |
+----------+

$ dolt sql -q "select count(*) from revision"
+----------+
| count(*) |
+----------+
| 4013041 |
+----------+

$ dolt sql -q "select count(*) from comment"
+----------+
| count(*) |
+----------+
| 1409589 |
+----------+
```

Seems like something should have gotten written to disk.
