Comment (by nomeata):

 This seems to be an instance of the problem described at http://www
 .joachim-breitner.de/blog/archives/620-Constructing-a-list-in-a-Monad.html
 (for which I have not found a suitable solution yet).

 Have you tried passing an a dlist in the accumulator? OTOH, it shouldn’t
 perform better than your first patch, just result in a different order...

 You say you use 7.8. Does this mean that the rumors that the stack would
 be unlimited in 7.8 are not true?
