SQLite CVSTrac

Here is a list of things that the core SQLite developers want to work on in the near future:

SAVEPOINT and nested transactions
Enforce foreign key constraints.
- Omit support for deferred constraints
- Omit support for CASCADE
Rewrite the VDBE to be a 3-address machine rather than a stack-based machine
Use merge-sort like algorithms to make large inserts into indexed tables run faster
