The performance overhead of call() and yield() are comparable to 
function calls because it's simply a few register assignments in each 
case. (Change the stack pointer, etc.)

Memory overhead is memory for call stack, size of which can be 
determined by the programmer.

Am I right understand that every yield(ed)/blocking function is 
delegate to processing in system thread?

But what will be if our code would do a lot of blocking 
functions? All of them will be delegate to system threads? If how 
many system threads will be used? I am asking because it will 
look like that in system threads we will get same problem that 
was solved by fibers.
