C++ stackless co-routines are pretty lightweight. A few years back, when I was writing something for a presentation, I spun up 50 million coroutines, and arranged them in a ring with channels and passed a value all the way from each co-routine to the other, on Windows Laptop with 8GB of RAM. I don't recall the exact amount of memory used, but my laptop handled it really well.

That's stunning, if (honest if, I really don't know the answer) they consume 4K memory each, that would be 50M * 4K = 200G.

  They just use what you need for the variables. In this case, I didn't have anything heavy weight, so maybe only a few tens of bytes per co-routine.
