Ian/Simon(s) Thanks - looking forward to the fix.

I've now pushed it to the HEAD.

It will help with the real time enviroment that I've got.

Lazy evaluation and GHC's garbage collector will probably cause headaches if you want true real time stuff.

Follow on query: Is there a way of seeing the value of this interval from within the Haskell program? Helps in the calibration loop.

I don't follow - what interval do you want to know? You can't find out how long threadDelay took, but the lower bound (in a correct implementation) is what you ask for and the upper bound is what you get by measuring it, as you did in your original message. Thanks Ian
