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 just checked that the memory allocated with Foreign.ForeignPtr.mallocForeignPtrBytes is included in the GC stats. Does the FastString library use its own implementation of mallocForeignPtr? Best regards Tomasz
