I'm not sure about silently downcasting ssize_t to int. Maybe a check at runtime would be safer, but I'm too lazy to write complex code to handle errors :-) What do you think @serhiy-storchaka? Is it ok to rely that a stack will not be larger than 2 GB?

I think it is safe. This difference should be limited by co_stacksize which has type int.
