[Haskell-cafe] Memory usage outside of the Haskell heap

How can I profile memory usage outside of the Haskell heap? I'm using  
FastStrings for everything and some folks on #haskell suspect it  
might be causing my problems.

hGet :: Handle -> Int -> IO FastString
hGet _ 0 = return empty
hGet h i = do fp <- mallocForeignPtr i
               l  <- withForeignPtr fp $ \p-> hGetBuf h p i
               return $ PS fp 0 l

I do this a lot and the finalizers might not be running or something  
like that.

	Thanks, Joel
