Subject: Forcing a GC run

Hi,

How can I force that the GC frees all unreferenced objects? Basically
what I want is:

  x = Object.new
  xoid = x.object_id
  ObjectSpace.define_finalizer(x, proc { puts "recycled" })

  x = nil 
  ObjectSpace.garbage_collect
  puts "after GC"
  p ObjectSpace._id2ref(xoid)

What I get is:

  before GC
  after GC
  #<Object....>
  recycled

Where I'd have expected:

  before GC
  recycled
  after GC
  -> exception RangeError

Any hints?

Regards,

  Michael
