[Haskell-cafe] hxt memory useage

Hi, I've been using hxt to process xml files. Now that my files are getting a bit bigger (30m) I'm finding that hxt uses inordinate amounts of memory. I have 8g on my box, and it's running out. As far as I can tell, this memory is getting used up while parsing the text, rather than in any down-stream processing by xpickle. Is this a known issue? Matthew
