If the content of the patch is correct, it looks ready to apply, with only a touch of editing. Do we have a resident expert of sqlite3? Or Laszlo, do you have a reference for the statements made?
Sorry, the only reference I have is that mailing list thread (
http://mail.python.org/pipermail/python-list/2010-March/1239374.html ).
There you can find an example with SQL statements, showing the problem.

I have a theory, based on a quick perusal of the sqlite3 bindings
source.
The bindings think that "SAVEPOINT sp1" is a "non-DML, non-query"
statement. So when isolation_level is something other than None, this
statement implicitly commits the current transaction and throws away
your savepoints!

So the problem is with the sqlite binding code, not sqlite itself. I'm not an expert in C, so I'm not sure I can help more.
Thanks,
Laszlo
