2. You have to take the data out of an MVar to read it. In other words, only 1 thread can read an MVar at once [by design]. This isn't truly a problem in the current case, but it's irritating in principle that I can't make it so that once the cell is written, multiple threads can read it simultaneously...
This is also known as I-structures i.e. IVar. I think you can simulate them via MVar with the readMVar function? Regards, apfelmus
