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.

You can attach a print message to the finalizer and also print a message out when creating the string. I've found this to be helpful at times. -- David Roundy http://www.darcs.net
