[Haskell-cafe] system in forkIO

[Marco Túlio Gontijo e Silva]

Hello.

> import System.Cmd
> import GHC.Conc
> 
> main :: IO ()
> main
>   = forkIO
>     ( do
>         putStrLn "fork"
>         system "ls"
>         return ())
>     >> getChar
>     >> return ()

When I run this code, I get

fork

and the result of ls only after I press a key.  Does getChar blocks the
other threads?

Greetings.
