I remember once going through all sorts of pain trying to avoid

Then what you need is the new Data.Map clone..
http://darcs.haskell.org/packages/collections-ghc6.6/Data/Map/AVL.hs
which I believe has all the strictness control you could want.
Which is also on hackage,
http://hackage.haskell.org/cgi-bin/hackage-scripts/package/collections-0.3
Actually it isn't I'm afraid. That module has had a complete re-write
since the package was last cabalised. Anybody who's interested should
darcs get it from
http://darcs.haskell.org/packages/collections-ghc6.6/
