The fact that the API exists doesn't mean it's convenient to be used at any moment. gtk_clipboard_store uses a nested main loop with a timeout of 10 milliseconds. The nested main loop uses the default main context, so any other sources sent to the default main context (like an IPC message handler) would be handled by the nested main loop. That can cause problems, I had a lot of issues with the nested main loop used by gtk_enumerate_printers, because it handled other sources, for example. So, the safest way to use this API, which is how everybody uses it (included firefox for example), is to call it when the application finishes, right after the main loop quits.
