Thanks all.
If that is the case, in below code main go routine will a reach a situation
where no other go routines running to wake it up.
But no deadlock is not detected.
https://play.golang.org/p/z1NMYQAi0KY
May I assume deadlock - detection couldn't pick up this scenario?
By using empty select{}, doesn't the coder purposely wishes to block
forever?
Thanks, Aravindhan K
