Normally, all messages are on the main loop. Although apps can run separate 
threads, the OS loop is always on the main thread (that's why it's so delicate 
for us, because R also runs on the main thread so the two loops must be meshed 
together without blocking each other).

Can you send me a reference to the issue, please? I'll try to find some spare 
cycles to look into it later this week.

Thanks,
Simon
