Thanks for the explanation, I made it working. I have a window with both a background counter and [+] and [Reset] button that interact with it :)
It's incredible how fast is Lua/Lgi learning curve :D

I googled to

while (gtk_events_pending())
gtk_main_iteration();

but I didn't tried yet.

I didn't tried yet co-routines. But when you said "resumed", it means the co-routine will restart from where it was interrupted and I don't have to manage context or such. I mean like an OS task is interrupted by an IRQ ?
I'll have to learn also how to interact with the co-routine. Signal ? Semaphore ???
