[Chicken-users] Garbage collection

[Zbigniew]

I was wondering if csi keeps some kind of hidden reference to objects
you create.  Heap memory never seems to get freed, as shown below. 
Running this code as an executable, or compiling it into a shared
library and running that in csi, does free the memory.
