as Udo said, it should be better to evaluate thunks just when they are

While I understand why you and Udo are right, still it is difficult

No. The state cannot become garbage, because there is still a reference
to it. As long as runStateT has not returned, any part of the state can
still be

Thanks a lot for stopping by.

The correct solution however, is the application of 'seq' at the right
places. To understand where these are, perform a simulation of
Haskell's reduction strategy on paper.

I'm a newbie and, as a learning experience, I'm writing a feed reader

a Liferea cache but, as you can imagine, I'm running into the usual
