Maybe you could try a lazy version of mapM?  E.g., I think this would do
it:
Another option is to use a version of mapM that accumulates the result
on the heap.  Maybe this would do the trick:

mapM' f = go []
  where
    go acc [] = return (reverse acc)
    go acc (a:as) = do {x <- a; go (x:acc) as}
