  I thought you said you had deleted the object and two global GC's in a
  row were still pretty slow?  I can't reproduce that.  global GC takes the
  same time no matter how much free space there is in the old space.

  Attention, Republican members of the House Judiciary Committee!  We have
  intercepted a coded transmission from Bill Clinton to Saddam Hussein that
  puts your life in jeopardy.  Clinton is prepared to cease fire if all of
  you are killed by Iraqi terrorists, whom he won't prosecute.  Be warned!
