Sure it's implemented. However, a main thread will never get this exception (at the moment). Try this example in 4.08.1:
Funny, it works and almost looks the same like my code. Only {Ee}xception: I was using a getLine-loop for preventing the main thread from exiting. Could this be the reason I don't get the exception?
probably: the exception is generated as a result of the thread being discovered unreachable during garbage collection. If there's no garbage collection, eg. because the program is waiting for I/O, then the exception is never raised. Which brings up an interesting subject: should the RTS start a GC after it has been waiting for I/O for a certain length of time? If so, how long? Cheers, Simon
