run_in_thread
Description:
Runs task_func in another thread.
When task_func returns, this's
TaskReadyCallback will be invoked in this's
MainContext.
This takes a ref on this until the task completes.
See TaskThreadFunc for more details about how task_func is
handled.
Although GLib currently rate-limits the tasks queued via run_in_thread, you should not assume that it will always do this. If you have a very large number of tasks to run (several tens of tasks), but don't want them to all run at once, you should only queue a limited number of them (around ten) at a time.
Be aware that if your task depends on other tasks to complete, use of this function could lead to a livelock if the other tasks also use this function and enough of them (around 10) execute in a dependency chain, as that will exhaust the thread pool. If this situation is possible, consider using a separate worker thread or thread pool explicitly, rather than using run_in_thread.
