[Thread_GetCurrentID] returns the ID of the thread which represents the current Lasso page.

Each thread in Lasso represents either a browser initiated page load or an asynchronous tag or compound expression. The [Thread_List] will always include one ID which represents the current page load (also returned by [Thread_GetCurrentID]) and usually will also have IDs for the background processes in Lasso which manage the email queue, event scheduler, and session manager.
