[Haskell-cafe] Data.Complex.magnitude slow?

i've attached an example program which seems to indicate that the  
magnitude function from Data.Complex is very slow compared to a more  
naive implementation (for Complex Float). on my machine (intel core2  
duo, osx 10.4) the CPU time using the library function is about 6-7  
times as much as when using the other function. any ideas what might  
be going on? any flaws in my measurement code?
