hmmm, thought of something else: I assume your application makes
extensive use of GOOPS.  then it could just be that the heap is much
larger with the newer Guile -- structs became twice fatter not very
long ago.

... it's just that in C++ and the like, you don't trust _anybody_,
and in CLOS you basically trust everybody.  the practical result
is that thieves and bums use C++ and nice people use CLOS.
