I am looking to implement a sort of 'activity log' table where actions a user does are stored in a sqlite table and then presented to the user so that they can see the latest activity they have done.

I have a sqlite3 database that is accessed by a few threads (3-4). I am aware of the general limitations of sqlite3 with regards to concurrency as stated http://www.sqlite.org/faq.html#q6 , but I am convinced that is not the problem.
