Maybe I did not fully understand this answer.<br> If this is referring to my note regarding the need for shared-memory then I will emphasize: generally speaking shared-memory is only needed for sharing data between different processes. If a single process wants to share data between its various threads it can do so using heap memory or any other process-internal memory. Since my application is using the database exclusively I thought that sqlite implementation will not need shared-memory per se (unless if it is hard-wired to do so).
