it may be problem with something else. in particular, check that
you don't have lazy thunks stored instead of values

data.hashtable. at least, i can calculate its memory usage - it should
be less than 100 bytes per key even with collecting GC. plus memory
required for values

...but intmap should be the same. i still think that you have unforced
thunks stored in map
