First of all, there's a difference between multiprocessing (multiple processes) and multithreading (multiple threads within one process).

It seems that you're talking about multithreading here. There are a couple of caveats that you should be aware of when using SQLite in a multithreaded environment. The SQLite documentation mentions the following:

• Do not use the same database connection at the same time in more than one thread.
• On some operating systems, a database connection should always be used in the same thread in which it was originally created.
