Re: [Haskell-cafe] Getting the 'ThreadId' of the calling thread

I feel that a 'myThreadId' action, which is defined in this module [1], is useless, but I'm not sure. I think it will always return the "Map.find: element not in the map" exception because a 'threadMap' contains an empty 'ThreadMap'.

Is it right, or am I missing something?

Other actions such as withLinksDo and forkLinkIO' insert stuff into threadMap. It can be non-mepty.
