Perhaps after you do a '(gc)' ? Since chicken does it's own memory
management, and gc is only done after a certain amount of
garbage has accumulated, that release of storage may be delayed.

Also, the heap may be resized during execution and grow larger
and smaller on demand - again, this may be delayed for a short
while.
