Sorry but I cannot agree with the logic behind this statement, 
the whole point of using fiber is that, spwaning system thread is 
expensive, thus ppl create lightweight thread 'fiber', then if a 
'fiber' is still considered expensive, should ppl invent 'giber' 
on top of 'fiber', then 'hiber' on top of 'giber'? That will be 
infinite.

If you mean 'each fiber has its own stack' by 'expensive', to be 
fair, golang's goroutine is stackful (4KB stack for each 
goroutine), it's like >50X faster with the same test case.
