alternatives to Firebird: sqlite [was: Firebird doesn't support MSVC 2015]

I understand, but the situation with Firebird seems less than ideal, at least in terms of Windows builds at any rate.
Are the tests really that much slower? Obviously we are relying on having a Java installation to test out Base.
Can we isolate those things that we can test on sqlite to sqlite, and any other things to HSQLDB2 or H2? If/when sqlite or some other more appropriate embedded database comes along, then we can consider switching.
Oh, and I’m not sure if this brings much to the table, but I wonder if we can simulate joins. After all, to get a right join you just swap tables, and you can actually simulate a full outer join with just a combination of other joins.
