[Haskell-beginners] Safe TCP accept loop

[Sumit Raja]

Hello,

I’ve looked at https://wiki.haskell.org/Concurrency_demos/Graceful_exit and used(2) Using throwTo without the use of block and unblock. It runs on 8.2.1 with my limited testing. I can’t find out much about what the  > 7.x GHC replacement for block/unblock is other than mask. What does the unblock do in acceptConnections'?

Does this method of handling an accept loop still need masking of async exceptions ? If so where does this need to be done? 

Thanks

Sumit
