Ok, but I would expect after assigning a nill, and calling the GC
explicitely that it released memory :-(
Nothing links to the object anymore.
(I use big C++ objects coupled with Ruby classes, so the ruby-side is very
small)


I changed the simple example to:
#====================
class Example
end

1.times {    # << added this
  a=Example.new
  p ObjectSpace.each_object(Example) { }
}
GC.start
p ObjectSpace.each_object(Example) { }
#====================

It prints 1 and 0
Then the GC kicked in :-) , probably because of the scope?
If 1.times { ... } is leaved out it prints 1,1.
Is there any trick to enforce the GC to release memory?
